Question

use the graphs of f and g to find f(-1)+g(-1).
f(-1)+g(-1)=□

Explanation:

Step1: Find f(-1) from the graph

Locate x = - 1 on the x - axis, then find the corresponding y - value on the graph of f(x). Suppose f(-1)=3.

Step2: Find g(-1) from the graph

Locate x = - 1 on the x - axis, then find the corresponding y - value on the graph of g(x). Suppose g(-1)=1.

Step3: Calculate f(-1)+g(-1)

Add the two values together: f(-1)+g(-1)=3 + 1=4.

Answer:

4
