Answer:
x + 6

Edit:
A moderator mentioned my answer had a mistake: turned out the question posted was incomplete. The complete question should read:
"
What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?
x – 6
x – 3
x + 1
x + 6
"
As shown in the same graph, f(x) cross the x-axis at x = -6, -3 and 0.
When a polynomial crosses the x-axis at x = a, (x - a) must be a factor.
So (x + 6), (x + 3) and x are factors of f(x).
Of the options, the correct answer is x + 6.
