Answer:
Option D.
Step-by-step explanation:
The given graph represents the function f(x).
If graph of a function f(x) intersect x axis at x=c, then (x-c) is a factor of f(x).
From the given graph it is clear that the graph of f(x) intersect x axis at x=-6,-3,0. It means factors of given function are
[tex](x-(-6))=(x+6)[/tex]
[tex](x-(-3))=(x+3)[/tex]
[tex](x-0)=x[/tex]
It means (x+6), (x+3) and x are factors of given function.
Therefore, option D is correct.
