The monthly revenue of a digital magazine from each user is represented by f(x) = 5x + 1. the monthly cost to provide the digital magazine to each user per month is represented by g(x) = x + 2. which of the following functions can be used to evaluate the profit for each user? (f – g)(x) = (5x + 1) – (x + 2) = 4x – 1 (g – f)(x) = (x + 2) – (5x + 1) = –4x + 1 (f + g)(x) = (5x + 1) + (x + 2) = 6x + 3 (g – f)(x) = (x + 2) – 5x + 1 = –4x + 3
