Question 1

Which of the following is the domain of the function shown in the first graph?

Accepted Answer

$$\{-4, -2, 0, 2, 4\}$$

Question 2

Which of the following is the range of the function shown in the first graph?

Accepted Answer

$$\{0, 2, 4\}$$

Question 3

Based on the first graph, is the relation a function?

Accepted Answer

Yes, because each input has exactly one output.

Question 4

For the function in the first graph, what is $$f(2)$$?

Accepted Answer

$$2$$

Question 5

For the function in the first graph, list all input values where $$f(x) = 2.$$

Accepted Answer

$$x = -2$$ and $$x = 2$$

Question 6

What is the value of $$f(0)$$ for the function shown in the first graph?

Accepted Answer

$$4$$

Question 7

Which of the following best describes the symmetry of the function in the first graph?

Accepted Answer

The function is symmetric about the y-axis.

Question 8

Estimate the solution to the system of equations shown in the third graph (intersection point).

Accepted Answer

$$(6, 4)$$

Question 9

In the third graph, what is the approximate y-value where the two lines intersect?

Accepted Answer

$$4$$

Question 10

In the third graph, which line has a greater slope?

Accepted Answer

The red line

Question 11

If the blue line in the third graph represents $$y = mx + b$$, what can you say about $$m$$?

Accepted Answer

$$m is $$positive and less than the slope of the red line.

Question 12

If the red line in the third graph is steeper than the blue line, what does this indicate about their slopes?

Accepted Answer

The red line has a greater absolute value of slope than the blue line.
