Answer:

(f•g)(10)= 606

Explanation:

We have been given that

$f(x)=x^2+1\\\\g(x)=x-4$

We have to find the value of (f•g)(10)

We can write (f•g)(10) = f(10)•g(10)

Let us find the value of the functions at x = 10

$f(10)=10^2+1\\\\f(10)=100+1\\\\f(10)=101$

And the value of g(10) is

$g(10)=10-4\\\\g(10)=6$

Hence,

(f•g)(10)

= f(10)•g(10)

= 101×6

= 606

Therefore, (f•g)(10)= 606
