What is X3 - X?

Answer 1

This depends on what you mean by "X3". If the equation is x3-x, then the graph would increase up to about y=0.385, crossing the x-axis at x=-1, then decrease to y=-0.385, crossing the origin, then begin to increase again, crossing the x-axis at x=1.

If you just mean x*3-x, then the answer would be 2x.

You just enter the function in as f(x)=x^3-x and it will tell you the graph.

For future reference, x3 is x^3, not x3.
