Question

Answer 1

Hello @_dianaelena and Welcome to OpenStudy!

Sorry for the late reply :-/

g(f(x)) means that you plug in f(x) as "x" in the g(x) equation

so we can get
G(f(x)) = (2x-5)^2 + 1
= (2x - 5)*(2x - 5) + 1

from there all you have to do is FOIL and add like terms
to get your answer :)

I hope this helped <3
