Question

Use the graph to determine a. the function's domain; b. the function's range; c. the

x-intercepts, if any; d. the y-intercept, if there is one; e. the following function
values.
f(-3)
f(0)
7-8-5-4-3-2-1
Q
2

Answer 1

Part a

The domain is the set of x-values, which is
`(-\infty, \infty)`

Part b

The range is the set of y-values, which is
`(-\infty, -2]`

Part c

The x-intercepts is when y=0, which there are none of.

Part d

The y-intercept is when x=0, which is at (0, -2).
