Question

Evaluating Functions in Graphical Form

Answer 1

Step-by-step explanation:

Step 1:  Find the value of f(-1)

Using the graph, locate where x = -1.  We can see that when x = -1, y is equal to about -8.  Therefore, f(-1) = -8.

Step 2:  Find the value of f(1)

Using the graph, locate where x = 1.  We can see that when x = 1, y is equal to about -12.  Therefore, f(1) = -12.
