Find f(g(4))

Answer 1

We need to first find the value of g(4), and then substitute that value into the function f.

Given:
g(x) = x^2 + 3
f(x) = 2x - 1

First, find g(4):
g(4) = 4^2 + 3
g(4) = 16 + 3
g(4) = 19

Now, substitute g(4) = 19 into the function f:
f(g(4)) = f(19) = 2(19) - 1
f(g(4)) = 38 - 1
f(g(4)) = 37

Therefore, f(g(4)) = 37.
