Question

Find the following f(g(x)) when f(x)=2x+4 and g(x)=2x

Answer 1

Answer:

4 + 4x = f(g(x))

Step-by-step explanation:

According to the compositional function, we plug the g(x) function into the f(x) function in replacement for every x we see:

$2(2x) + 4 = 4x + 4 \\f(g(x)) = 4x + 4$

The above answer is written in reverse, which is the exact same result.
