g(f(x)) means that the function g is composed at the function f.
You need to plug the value of f(x) into the function g and simplify.
g(x) = 2x - 1
Replace x with the value of f(x) which is 3x - 2 and simplify.
g(f(x)) = 2x - 1
g(3x - 2) = 2(3x - 2) - 1
g(3x - 2) = 6x - 4 - 1
g(3x - 2) = 6x - 5
So, g(f(x)) = 6x - 5
