If f(x) = 3x + 3, g(x) = 3x + 3, and h(x) = x + 3, what is [go fo h](-5)

-6

[g o f o h](-5) means the same as g(f(h(-5)))
Just like a normal math problem you start at the inner most part—h(-5). Then use the answer(-2) for the next inner part—f(-2). Finally that answer is used for the outer most part—g(-3). Which comes to -6.
