Find the derivatives of the following functions using the power rule. Groups I. f (x) = x I1. f (ac) = 526 Ill. f (ax) = 24 -723 Calendar B. A grocery store is open for 10 hours. The number of customers that are in a grocery store after t hours of being open is given by the function C (t) = 20t - 2t2. If you Inbox graph this, you'll see the store gets more and more customers until a certain point, where the customers then start to decrease. I. Find the vertex of this parabola by using the equation t = -b/2a. What History coordinate pair (t,C(t)) is the vertex located at? Il. Take the derivative of C(t) and set it equal to zero.
