Try this.
f(x) = (x+1)^2
g(x) = (x+2)
He didn't say that was the answer! That is a completely different problem. He was just trying to remind you of what f(g(x)) means!
f(g(0))= 5 because, according to the table, g(0)= 2 and then f(2)= 5.
f(g(0))= f(2)= 5
To find f(g(1)), note that g(1)= 0 and f(g(0))= f(1)= 1.
To find f(g(2)), note that g(2)= 1 and f(g(2))= f(1)= 9.
To find f(g(2)), note that g(2)=
