We have been given a graph of a upward opening parabola. We are asked to find the factors of given parabola.

We can see from our given graph that zeros of our equation are
x=-2 and
x=5 .

We know that when
x=a is a zero of a polynomial, then
(x-a) is factor of the polynomial.

Let us find factors of our given function.

x+2=-2+2

x+2=0

Therefore,
(x+2) is a factor of our given function.

x-5=5-5

x-5=0

Therefore,
(x-5) is a factor of our given function and option D is the correct choice.
