When a food culture is removed from a refrigerator (at 34° F), it takes 3 hours = for the culture to get to room temperature (70= ° F). The temperature t hours after being removed is giv= en by

 

        &= nbsp;   T(t) =3D 1= 2t + 34            = ;            0 < t < 3

 

The number of bacteria in the food culture is based on the temperature. The num= ber N(T) of bacteria at temperature T is given by
