    You set up an equation. The form is y=ax^2+bx+c. For each set of points starting with (0,0) You plug in for y and x. That is how you get started.

    Have you learned matrixes yet? Because you can use your calc to solve that... If not just set up 3 equations where you replace y=ax^2+bx+c, and then you can either substitute or cancel.
