You can put this solution on YOUR website!
If the vertex is (2,-12) and it passes through the origin, then symmetry says it must also pass through (4,0).
The general form of a parabola function is
So, if  when  , then

and if when  , then
Solve the 3X3 linear system to get the coefficients a, b, and c. Use them to write your equation by substituting into:
