(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

So i have a parabola graphed, i need to express y in terms of X. The vertex is 2,10 and the roots are 0,0 and 4,0.

2. Relevant equations

ax^2+bx+c=y

quadratic

3. The attempt at a solution

I thought of working the quadratic in a reverse process, but it doesn't work. Because one of the roots is at 0,0, i guess it doesnt have either b or c. Because the paraboal is upwards and not downards, i guess X must be negative.
