Cubic Function
Cubic function is a little bit different from a quadratic function.Cubic functions have 3 x intercept,which refer to it's 3 degrees.This is an example of a cubic function y=(x-1)(x+3)(x-4).As you have learned previously,it has 3 x intercepts which located on (1,0)(-3,0)(4,0).
That's how it looks on a graph.(i have to change my graphing program because the previous one doesn't support a cubic function,sorry about the change.)
