Find the quadratic function that has vertex (10, -7) and whose graph goes through the point (5, 168).
Vertex form of a parabola is:
y=a(x-h)2+k; where (h,k) is the vertex
Vertex is given, plug them in.
Now we need to find the value of a.
Graph goes through (5,168), so plug those into x and y to solve for a.
With that, we now have the function of the parabola.
