Answer:
39
Explanation:
This weird notation just means we are going to put one equation inside the other, and then solve.
Makes more sense when you write it like this:
g ( f ( x ) )
To solve, we are going to take the 3, plug it into the f ( x )
g ( f ( 3 ) )
^ This makes it a lot easier to understand what we have to do.

Ok, so now we evaluate f ( x ) at 3.
4 ( 3 ) - 2
f( x ) = 10
Then we plug it into g ( x )
4 ( 10 ) - 1
= 39
Here's how it looks in total:
4 ( 4 ( 3 ) - 2 ) - 1 = 39
Slightly more complicated, but that's why i broke it down step by step.
