The number of bacteria in a refrigerated food product is given by $\displaystyle {N}{\left({T}\right)}={25}{T}^{{2}}-{82}{T}+{31}$, $\displaystyle {3}<{T}<{33}$ where $\displaystyle {T}$ is the temperature of the food.
When the food is removed from the refrigerator, the temperature is given by $\displaystyle {T}{\left({t}\right)}={4}{t}+{1.4}$ , where $\displaystyle {t}$ is the time in hours.

Find the composite function $\displaystyle {N}{\left({T}{\left({t}\right)}\right)}$:
$\displaystyle {N}{\left({T}{\left({t}\right)}\right)}=$ Preview Question 6 Part 1 of 2
