f(x) = g (g(x))

g (g (x)) means that we sub g(x) into itself....so we have that

g(g(x) ) = 2 (2x - 1) - 1 =

4x - 2 - 1 =

4x - 3

So....since this is f(x)

Then f(3) =

4(3) - 3 =

12 - 3 =

9

Chris just forgot the -g(x) portion of f(x)

so he got 9 fpr the first part...

9 - (2(3)-1)

9-6+1 = 4
