Cubic function

In mathematics, a cubic function is a function of the form

Bipartite cubics

The graph of

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:y^2 = x(x-a)(x-b),

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

where 0 < a < b is called a bipartite cubic. This is from the theory of elliptic curves.

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

You can graph a bipartite cubic on a graphing device by graphing the function

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:f(x) = sqrt{x(x-a)(x-b)},

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

corresponding to the upper half of the bipartite cubic. It is defined on

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:(0,a) cup (b,+infty).,
