Answer:

-62

Explanation:

Two functions are given to us , which are ,


\bf\implies f(n)= -n \\\\\bf\implies g(n)= n - 2

We need to find , ( f • g )(8) . So ,

⇒ ( f • g) = - n ( n - 2 )

⇒ ( f • g) = -n² + 2

(f g) = 2 -

==================================

Substituting n = 8 :-

⇒ ( f • g)(n) = 2 - n²

⇒ ( f • g)(8) = 2 - 8²

⇒ (f • g)(8) = 2 - 64

( f g)(8) = -62 .

Hence the required answer is (-62) .
