Question 1

Given the relation represented by the mapping diagram in Image 1, which of the following statements is true?

Accepted Answer

The relation is not a function because at least one input is paired with more than one output.

Question 2

Which of the following best describes the graph in Image 2?

Accepted Answer

The graph represents a quadratic function that opens downward.

Question 3

Based on the graph in Image 3, what is the domain and range of the relation?

Accepted Answer

Domain: $$[-4, 4]$$, Range: $$[-3, 3]$$

Question 4

Does the graph in Image 3 represent a function? Use the vertical line test to justify your answer.

Accepted Answer

No, because some vertical lines intersect the graph more than once.

Question 5

Which of the following equations best matches the graph in Image 10?

Accepted Answer

$$y = -\frac{4}{3}x - \frac{23}{3}$$

Question 6

What is the slope and $$y-$$intercept of the line shown in Image 10?

Accepted Answer

Slope: $$-\frac{4}{3}$$, $$y-$$intercept: $$-\frac{23}{3}$$
