can someone help me with this and explain it to me step by step so i can try to solve the remaining problems i have I have no idea of what I am supposed to do
For each problem, construct two composite functions, . Evaluate each composite function for x=2.

f(x)=x^2: g(x)=x-1/x

1. Steve

f(g) = g^2 = ((x-1)/x)^2
f(g(2)) = (1/2)^2 = 1/4

similarly for g(f)
