Bacteria tend to grow very fast in a Petri dish at first because of unlimited food and then begin to die out due
to competition. In a certain culture, the number of bacteria is given by N(t)=-2°+92 +625, where !
represents the hours since 625 bacteria were introduced to the Petrì dish. Determine the maximum number
of hacteria that occur in the dish.
