Cubic Interpolator

Like the quadratic interpolator, the cubic interpolator is based on a polynomial expression. Cubic

functions can produce more complex curves than quadratic functions, and are characterized by having a

vertical point of inflection. That is to say, they go up, then down, then back up again.

Cubic functions are of the form.

ax
3
+ bx
2
+ cx + d = 0
