Find numbers a. b, and c that the graph f(x) = ax^2 + bx + c has x-int (0,0), and (8,0) and a tangent with slope 16 where x = 2.

OpenStudy (anonymous):

I can already tell that c = 0 . I also know that the derivative of the function f(x) would be 2ax + b < -- f'(x)

OpenStudy (anonymous):

16 = 2ax + b

You have two equations 64a+8b=0 and 4a+b=16
