Answer:
4
Step-by-step explanation:
[tex]h(x)=x-7 \\\\g(x)=x^2 \\\\(g\circ h)(5)= (5-7)^2=(-2)^2=4[/tex]
Hope this helps!
Using composite functions, it is found that the equivalent expression at x = 5 is given by:
[tex](g \circ h)(5) = 4[/tex]
A composite function is when a function is used as an input to another function, hence, that is:
[tex](g \circ h)(x) = g(h(x))[/tex].
In this problem, we have that the functions are given as follows:
Then, the composite function is given by:
[tex](g \circ h)(x) = g(h(x)) = g(x - 7) = (x - 7)^2[/tex].
We want to find the value of the composite function at x = 5, hence we have that:
(5 - 7)² = 4.
