3. The elevation of a hiker (in hundreds of feet) t hours after she starts a hike is given by the function f(t) = t* – 9t³ + 23t² – 15t + 20 for the five hour hike. (a) What is the hiker's elevation when the hike begins? (b) When will the hiker's elevation be over 2000 feet? (c) What is the highest elevation reached by the hiker? When does she reach it?
