use the graph to evaluate the function for the given input value.\nf(-1) = \nf(1) =

Explanation:

Step1: Locate x = -1 on x - axis

Find the point on the graph where x=-1.

Step2: Determine the y - value

The y - value at x = -1 is - 5. So f(-1)=-5.

Step3: Locate x = 1 on x - axis

Find the point on the graph where x = 1.

Step4: Determine the y - value

The y - value at x = 1 is - 15. So f(1)=-15.

Answer:

f(-1)=-5 f(1)=-15
