The monthly revenue of a digital magazine from each user is represented by f (x) = 2x+15. The monthly cost to provide the digital magazine to each user per month is represented by g (x) = x2. Which of the following evaluates the profit function for each user of the digital magazine after 3 months?

(f - g) (3) = (2 (3) + 15) - 32 = 21 - 9 = $12

(g - f) (3) = 32 - (2 (3) + 15) = 9 - 21 = - $12

(f + g) (3) = (2 (3) + 15) + 32 = 21 + 9 = $30

(g - f) (3) = 32 - 2 (3) + 15 = 9 - 6 + 15 = $18
