Answer:
-1, 0 and 1
Step-by-step explanation:
Let's work through this step by step.
x goes from -2 to 2 so we will check each integer in between.
f(-2) and g(-2) is the first one. The table shows f(-2)=-8 and g(-2)=-2, so f(-2) does not equal g(-2)
Now we just keep doing this for x=-1,0,1, and 2
f(-1) = -1 and g(-1) = -1 so f(-1)=g(-1)
f(0)=0 and g(0)=0 so f(0)=g(0)
f(1)=1 and g(1)=1 so f(1)=g(1)
f(2)=8 and g(2)=2 so f(2) does not equal g(2)
So there were three xs that made f(x) = g(x). -1, 0 and 1, so those are your answers.
