Use the graph to find the value of f(x) when x = 9 for the function f (x) =
1
3
x − 3.

Step-by-step explanation:
this looks totally like
f(x) = 1/3 x - 3
to me.
because
f(0) = -3
f(3) = -2
f(6) = -1
so, f(9) = 1/3 × 9 - 3 = 3 - 3 = 0
f(9) = 0
you did not list that as answer option, but that is the correct answer.
