1. Write an equation of the quadratic function f whose graph has x-intercepts 3 and 7 and f(5) = 8.
2. I really don't know where to go from here
3. obviously, is the x-int. are 3 and 7 that means they are points (3,0) and (7,0). Also, f(5) = 8 becomes the point (5,8) which i have found to be the vertex. But, at this point, I don't know how to form a parabolic equation around those three points. Please help me!
