Question

For which pair of functions is (g circle f) (a) = | a | minus 2?

Answer 1

depends on what g and f are, but the best way to approach this is simply to go through each answer choice, evaluate (g ∘ f)(a), and see if it gives you |a| - 2

as a reminder, (g ∘ f)(a) means that you should evaluate f at a, then plug the result from that step into g
