Answer:
f(x)=-(x-5)^(2)(x+2)

Explanation:

There is a double root at x=5 and a single root at x=-2, so we know f(x) is of the form
f(x)=a(x-5)^(2)(x+2) for some constant a.

To find a, we can substitute the coordinates of the y-intercept, (0, -50).


-50=a(0-5)^(2)(0+2)\\\\-50=50a\\\\a=-1

So,
f(x)=-(x-5)^(2)(x+2)
