The problem is:(adsbygoogle = window.adsbygoogle || []).push({});

"In an electrical circuit, the voltage,Vvolts, as a function of time,tminutes, is given by V = 12 - 9t + 2t^2. Determine the greatest and least values of voltage during the first 5 min. When do these values occur?"

The answers given are exact.

Least: 1.875 V @ 2.25 min

Most: 17 V @ 5 min

Well I know how to get the max, but the min?

Thanks!!
