On a particular​ day, the power used in a particular
state​ (in thousands of​ megawatts) could be approximated
by the function
​P(t)=−0.006573t3+0.1918t2−1.082t+18.26
where t is the number of hours since​ midnight, for
0≤t≤24.
Find any relative extrema for power​ usage, as well as when
they occurred.
