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.
X3 X(X2) X2(X) and, X * X * X
x3
x3 + 8 = x3 + 23 = (x + 2)[x2 - (x)(2) + 22] = (x + 2) (x2 - 2x + 4)
x3 6x2-x-30
x3 + 2x2 - 35x = x(x + 7)(x - 5)
x3 + 1 = x3 + x2 - x2 - x + x + 1 = x2(x + 1) - x(x + 1) +1(x + 1) = (x + 1)(x2 - x + 1)

x3 - x2 + x - 2 has no rational factors.
x3-x2
x3 - 3x2 + x - 3 = (x2 +1)( x - 3)
x3 - 2x2 + x - 2 =(x - 2)(x2 + 1)
x3 - 3x2 + x - 3 = (x - 3)(x2 + 1)
