Question

(f ∘ g)(x) so if g(4) = 8 and f(8) = 22, then (f ∘ g)(4) =

Answer 1

Then (f ∘ g)(4) = 22

Explanation:

In order to find this, we first need to understand what (f ∘ g)(x) means. This statement means that we first plug our value in for the g(x) equation. After which, we take the result and plug it into the f(x) equation. The end result of that is the answer.

So, since we plug 4 in for x in g and get out 8 (as the beginning part states), then we know to put 8 in for the f(x) equation. This then yields 22, which is our answer.
