What program to graph non-linear equations.

It's me again with another question about graphing using a computer application.

I need to graph a non-linear equation with the plots (14,21) (9,34) (5,90).

What do I use for this? I'm trying to use Wolfram Alpha but it's not coming out he way I want to.

I'm not following.
Use a scatterplot and draw random lines in between the points?
Edit: Nvm, I get it.

Maybe this is what you want?

Or you could you get a system of equations, plug in the points for x and y and solve with matrices to find the function[/quote]

Ugh, I forgot how to do that. ><
