Answer:
Option A.
Step-by-step explanation:
The given question is incomplete. Let as consider we need to find [tex](g\circ h)(5)[/tex]
The given functions are
[tex]h(x)=x-7[/tex]
[tex]g(x)=x^2[/tex]
We need to find the expression for [tex](g\circ h)(5)[/tex].
[tex](g\circ h)(5)=g(h(5))[/tex]
[tex](g\circ h)(5)=g(5-7)[/tex] [tex][\because h(x)=x-7][/tex]
[tex](g\circ h)(5)=(5-7)^2[/tex] [tex][\because g(x)=x^2][/tex]
Therefore, the correct option is A.
