Answer:

f(x) = 3(x - 3)(x - 7)

Step-by-step explanation:

f(x) = A(x - 3)(x - 7)

Using (5,-12)

-12 = A(5-3)(5-7)

-12 = A(2)(-2)

-12 = -4A

A = 3

f(x) = 3(x - 3)(x - 7)

Step-by-step explanation:

Step 1:  Find the equation

Since the x-intercepts are at 3 and 7, the factors are going to be the opposite.  (x - 3) and (x - 7)

Since it is a stretched parabola, there is a number in front of the factors.

f(x) = 3(x - 3)(x - 7)
