Interactive math quiz visual for high school students using engaging cards for exam readiness.

Which of the following represents a linear equation with a slope of 2 and a y-intercept of 3?
y = 2x - 3
y = -2x + 3
y = 3x + 2
y = 2x + 3
The equation y = 2x + 3 clearly represents a line with a slope of 2 and a y-intercept of 3. The other options do not combine the correct slope and intercept.
Which equation represents a parabola that opens upward with its vertex at the origin?
y = x + 2
y = -x^2
y = x^2
y = 2^x
The standard quadratic function y = x^2 has its vertex at (0,0) and opens upward. The other options either open downward, represent a linear function, or an exponential function.
A card shows the sequence 3, 6, 9, 12, ... Which function correctly represents this pattern?
f(n) = n + 3
f(n) = 3n
f(n) = 2n
f(n) = 3^n
The function f(n) = 3n accurately generates the sequence by multiplying the term number by 3. The other functions produce sequences that do not match the given pattern.
If a card displays a bar graph with values 5, 10, and 15, which option correctly represents the mean of these values?
20
10
5
15
The mean of 5, 10, and 15 is calculated as (5 + 10 + 15) / 3 = 10. This is the correct average for the values provided.
A card shows a triangle with a base of 6 and a height of 4. Which formula correctly calculates its area?
6 + 4 = 10
1/2 * 6 * 4 = 12
6 * 4 = 24
6^2 + 4^2
The area of a triangle is calculated using the formula 1/2 * base * height, which gives 12 with a base of 6 and height of 4. The other options do not correctly calculate a triangle's area.
Given a graph showing a line passing through (0, 2) and (2, 6), which equation best represents this line?
y = 4x + 2
y = 2x + 2
y = 2x - 2
y = x + 2
Calculating the slope with the points given yields (6 - 2) / (2 - 0) = 2, and the line intercepts the y-axis at 2. Hence, the correct equation is y = 2x + 2.
If a card shows a parabola with vertex (3, -2) and opening upward, which equation in vertex form might represent it?
y = (x - 3)^2 + 2
y = (x + 3)^2 + 2
y = (x + 3)^2 - 2
y = (x - 3)^2 - 2
The vertex form of a parabola is given by y = a(x - h)^2 + k; with the vertex at (3, -2), the equation becomes y = (x - 3)^2 - 2. The other equations incorrectly position the vertex.
A card displays a table with inputs 1, 2, 3 and outputs 4, 7, 10 respectively. Which function best fits this data?
f(x) = x + 3
f(x) = 3x - 1
f(x) = 3x + 1
f(x) = 2x + 2
Testing the function f(x) = 3x + 1 gives f(1) = 4, f(2) = 7, and f(3) = 10, matching the table perfectly. The other functions do not yield the correct outputs for these inputs.
Which card representation corresponds to the formula for the area of a circle, A = πr²?
A rectangle with length r and width r
A square with side length r
A circle with the radius labeled r
A triangle with base r and height r
The formula A = πr² is specific to circles, so a visual representation of a circle with its radius marked is correct. The other shapes have different formulas for their areas.
A card shows the expression 4(2 + x). What is the simplified form using the distributive property?
8x + 4
4 + 2x
8 + 4x
2 + 4x
Applying the distributive property to 4(2 + x) results in 8 + 4x. The alternative options do not correctly distribute the multiplication over addition.
A card displays a graph that is symmetrical about the y-axis. Which type of function does this symmetry indicate?
Linear function
Exponential function
Even function
Odd function
Symmetry about the y-axis is a defining property of even functions, meaning f(x) = f(-x). The other types of functions do not necessarily exhibit this symmetry.
Using the points (1, 3) and (4, 15) shown on a card, what is the slope of the line?
8
12
4
3
The slope is calculated as (15 - 3) / (4 - 1) = 12/3 = 4. This correctly reflects the rate of change between the two points.
Which card best illustrates the function y = 2^x?
A graph that increases rapidly as x increases
A graph that decreases as x increases
A straight line with constant slope
A parabola opening upward
Exponential functions like y = 2^x increase rapidly as x increases, distinguishing them from linear or quadratic functions. The other options do not match the behavior of an exponential function.
A card states: 'Triple a number and then add 5 to get 20.' Which equation correctly represents this relationship?
x + 5 = 20
3x - 5 = 20
3(x + 5) = 20
3x + 5 = 20
The statement translates to multiplying a number by 3 and then adding 5, which forms the equation 3x + 5 = 20. The other options do not accurately reflect the order of operations described.
Which card best represents the concept of direct proportionality between y and x?
y = kx for some constant k
y = x + k
y = x^2
y = k/x
Direct proportionality means that y is directly related to x by a constant multiplier, expressed as y = kx. The other equations involve additional operations or relationships that are not purely proportional.
A card displays a graph of a function along with its equation f(x) = (x - 2)^2 + 1. Which description best explains the transformation from the parent function y = x^2?
The graph is reflected over the x-axis and shifted right by 2
The graph is shifted left by 2 and down by 1
The graph is shifted right by 2 and up by 1
The graph is stretched vertically by 2 and shifted up by 1
In the vertex form f(x) = (x - 2)^2 + 1, the graph is shifted 2 units to the right and 1 unit upward compared to y = x^2. The other transformations do not correctly match the modifications indicated by the equation.
A card presents a diagram with both a bar graph and a line graph representing two functions. If one function is given by f(x) = 2x + 1, which representation most likely corresponds to this function?
A line graph with a constant positive slope intersecting the y-axis at 1
A line graph that oscillates around the x-axis
A curve that starts low and then levels off
A bar graph with increasing discrete values
The function f(x) = 2x + 1 is linear with a constant slope and a specific y-intercept, which is best depicted as a straight line graph. The other representations fail to capture the linear nature of the function.
A card features two functions: f(x) = x + 3 and g(x) = 2x. What is the composite function f(g(x))?
2x + 3
2x + 6
2x - 3
x + 5
To form the composite function f(g(x)), substitute g(x) = 2x into f(x), giving f(2x) = 2x + 3. The other options do not correctly perform this substitution.
A card displays the quadratic function f(x) = -x^2 + 4 alongside a depiction of a projectile's path. What does this function indicate about the projectile?
The projectile's path is linear, so the quadratic function is incorrect
The projectile reaches a maximum height of 4, consistent with the vertex of the parabola
The projectile reaches a maximum height of -4
The graph represents exponential decay, not a projectile
The quadratic function f(x) = -x^2 + 4 has its maximum value at the vertex (0, 4), indicating the highest point reached by the projectile. The other answers misinterpret either the sign or the function's overall behavior.
A card set includes a scatter plot with a trend line whose equation is y = 0.5x + 2. What does the slope of 0.5 signify?
The function decreases by 0.5 with every step in x
For every increase of 1 in y, x increases by 0.5
The y-intercept is 0.5
For every increase of 1 in x, y increases by 0.5
A slope of 0.5 indicates that with each unit increase in x, the corresponding value of y increases by 0.5. The other interpretations incorrectly describe the slope or confuse it with the y-intercept.
