SOLUTION: Find the formula for the quadratic function whose graph has a vertex of (1,2) and passes through the point (-1,-6). Use the coordinates of the vertex to write p(x) in the form p

Question 955145: Find the formula for the quadratic function whose graph has a vertex of (1,2) and passes through the point (-1,-6).
Use the coordinates of the vertex to write p(x) in the form p(x)=a(x-h)^2+k (a unknown)
Use the coordinates of the second point to solve for a.
