Answer and Step-by-step explanation:
First, we plug in the value of 3 for x in g(x), then we plug the answer os g(x) into the value of x in f(x).
g(3) = 2(3) - 7
Multiply 2 by 3, then subtract 7.
g(3) = 6 - 7
g(3) = -1
Now, we plug -1 for x in f(x).
f(g(3)) = f(-1) = -1 + 1
f(-1) = 0
The value of f(g(3)) is 0.
