Please help me find the answer amongst the options below.

Answer:
3rd option (g o f)(x)=(x+1)^2
Step-by-step explanation:
we are given
f(x)=x+1
and
g(x)=[tex]x^{2}[/tex]
we have to find gof(x)=?
for gof(x) we will replace value of x from f(x) with g(x)
that is
(gof)(x)=[tex](x+1)^{2}[/tex]
hence it will be third option that is correct
