It appears that g(x) is constant, so it does not matter what f is.
Fix the typo. Then just substitute f(x) for x in the definition of g.
(g◦f)(x) = g(f(x))
That is, if g(x) = x+3,
(g◦f)(x) = g(f) = f+3 = 4x-5+3 = 4x-2
Use the functions f(x) and g(x) to answer the question.
F(x)=4x-5 ; g(x)= +3
Which expression is equal to (gof)(x)
4x+7
5x-2
4x-2
4x+12
Im not sure how to do this??

Thank you! I have to write that down for a example. I have others to do :)
Im trying to get it
Which expression is equal to (fog)(x)?
f(x)=3x-2 ; g(x)=x-4
I got 3x+6 ...
But thats not a answer chioicd the answer choicd close to it 3x-6
and the other options are
3x-14
3x^3+8
4x-6
