Question

Given f(g(x)) = 15x+1 and f(x) = 5x+1. What is g(x)?

Please answer quickly!!

Answer 1

Suppose you are given the two functions f (x) = 2x + 3 and g(x) = –x2 + 5. Composition means that you can plug g(x) into f (x). This is written as "( f o g)(x)", which is pronounced as "f-compose-g of x". And "( f o g)(x)" means " f (g(x))".
