One direction's percent of relevancy for 0 ≤ t ≤ 80 can be roughly modeled by the function p given by where p(t) is a percent and t is measured in months after od's debut. at approximately what time(s) t in the interval 0 ≤ t ≤ 80 does their career reach a maximum in relevancy? use a graphic calculator to solve this problem.

Arrange these numbers from least to greatest 3/5 5/7 2/9
