Question

A fitness center has set a goal to have 500 members. The fitness center already has 150 members and adds an average of 25 members per month. The function f(x) = 150+ 25x represents the membership after x months it will take for the fitness center to reach its membership goal. Is the function continuous or discrete? Explain.

Answer 1
