So this question is asking you to solve the equation you were given over a specific range of values. Those values are the x values, or the independent variable, from x=-2 to x=2.

The range is -2, -1, 0, 1, 2

y=(-2)^2=4

y=(-1)^2=1

y=0^2=0

And so on. To make a table, put the x values on the left and the corresponding y values on the right. In essence, pair -2 with 4, -1 with 1, 0 with 0, 1 with 1, and 2 with 4
