Question 910143
Vertex form is also called Standard Form.
{{{highlight_green(y=a(x-h)^2+k)}}}, the format for standard form for a parabola.


The vertex is (h,k).  The coordinates are given so you just substitute them.


Solve the equation for a.
Substitute the coordinates of the given NONvertex point and evaluate a.


Now you just substitute for what you found for a.
