Question
A parabola passes through the point (3, 5) on its way to the vertex at (7, 11). Determine the equation in vertex form that represents this parabola.

knowing the vertex, you know that
y = a(x-7)^2 + 11
So, using the other point, just solve for a in
5 = a(3-7)^2+11
y = a(x-7)^2 + 11
So, using the other point, just solve for a in
5 = a(3-7)^2+11
