x y
-2 -8
-1 -1
0 0
1 1

What have you done to start this problem? Have you plotted the points? Does the graph look like it might be a line? If not, what do you think it might be?

What have you learned about the equation of this kind of graph?

We really can't help you until we see what you have done, what you know, and what your specific questions are.

I plotted the points on the graph and it looks like the letter "U"

I think I got it. y=x^3 (x cubed)
