Final answer:

The composition function (f ∘ g)(x) computes the number of minutes in x weeks.

Step-by-step explanation:

The composition of functions, denoted as (f ∘ g)(x), is found by substituting the function g into the function f. In this case, (f ∘ g)(x) = f(g(x)).

Substituting g(x) into f(x), we have f(168x) = 60(168x) = 10080x.

So, (f ∘ g)(x) = 10080x.

This function computes the number of minutes in x weeks.

Answer:
(f \circ g)(x)=10080x , where x is the number of weeks.

It computes the number of minutes in x weeks.

Step-by-step explanation:

Given : The function defined by
​f(x) = 60x computes the number of minutes in x hours​, and the function defined by
​g(x) = 168x, computes the number of hours in x weeks.

Then , the composite function is given by :-


(f \circ g)(x)=f(g(x))\\\\(f \circ g)(x)=f(168x)\\\\(f \circ g)(x)= 60(168x)\\\\(f \circ g)(x)=(60*168)x\\\\(f \circ g)(x)=10080x

Hence, the required composite function is :


\(f \circ g)(x)=10080x , where x is the number of weeks.

Simply, the above composite function computes the number of minutes in x weeks.
