f(g(x)) You plug in g(x) for x

f(x) = 2x + 3

f(g(x)) = 2(g(x)) + 3

f(g(x)) = 2(4x - 5) + 3

f(g(x)) = 8x - 10 + 3

f(g(x)) = 8x - 7

g(f(x)) You plug in f(x) for x

g(x) = 4x - 5

g(f(x)) = 4(f(x)) - 5

g(f(x)) = 4(2x + 3) - 5

g(f(x)) = 8x + 12 - 5

g(f(x)) = 8x + 7

7 is incorrect. The answer should be -4. Here's how I'd derive it:

With , we should expect . If , then

Also,

so we should expect and

You seem to be taking

but this is not an identity.

8 is incorrect. Just a silly mistake, you swapped the order of the terms in the numerator. It should be
