You can put this solution on YOUR website! HOW DO YOU FIND A QUADRATIC FUNCTION'S MAXIMUM VALUE OR MINIMUM VALUE WHEN THE FUNCTION IS GIVEN IN INTERCEPT FORM?
------------
Intercept form:
y = a(x-h)^2+k
---
Vertex is at (h,k)
If "a" is positive, (h,k) is at a minimum
If "a" is negative, (h,k) is at a maximum
