use the graph to evaluate the function for the given input value. f(-1)= f(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 on the graph is 0. So, f(-1)=0.

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 on the graph is - 10. So, f(1)=-10.

Answer:

f(-1)=0 f(1)=-10
