Answer: 0
Explanation:
Start at -1 on the x axis number line. Then move vertically until reaching the function curve. You should arrive at (-1,2). This tells us that g(-1) = 2. In other words, the input x = -1 leads to the output y = 2.
Follow similar steps to find that g(1) = -2
Therefore, g(-1)+g(1) = 2 + (-2) = 0
