Question

Choose the expression that represents the indicated composition.

Answer 1

Answer:

(f º g)(x) = f(g(x)) = 10(x-3)

Step-by-step explanation:

Given : $f(x) = 10x$ ,  $g(x) = x-3$

To Find : (f º g)(x) = ?

Solution :

(f º g)(x) = f(g(x))

So,$g(x) = x-3$ and $f(x) = 10x$

Substitute x = x −3 in f(x)

So, (f º g)(x) = f(g(x)) = 10(x-3)

Hence (f º g)(x) = f(g(x)) = 10(x-3)

Answer 2

I got this one wrong so obviously it will show me the correct one and it is =10x-30
