Answer: 76

Explanation:

Similar to equations with multiple variables needing substitution, we will substitute the contents of f(x) in the g(x) function for 5x-4.

g(x) becomes
g(x)=3(5x-4)-2 .

To help us, we can simplify this to have only one x:

$g(x)=3(5x-4)-2\\g(x)=15x-12-2\\g(x)=15x-14$

Now, the question just needs us to plug in 6 for x

$g(6)=15(6)-14\\g(6)=76$
