On a particular day, the power used in a particular state (in thousands of megawatts) could be approximated by the function P(t) = - 0.006779t³ + 0.1986t² – 1.065t + 18.54 where t is the number of hours since midnight, for 0sts24. Find any relative extrema for power usage, as well as when they occurred. Find the derivative of P(t). P'(t) =D
