When a loaf of bread is removed from the freezer to thaw, the temperature of the bread increases. Graph each of the following functions on the interval $[0,50]$. Use $[0,100]$ for the range of $A(t)$. Use a graphing calculator to determine the function that best describes the temperature of the bread $A(t)$ (in degrees Fahrenheit) $t$ minutes after it is removed from the freezer, if the initial temperature of the bread was 30 degrees Fahrenheit.
(a) $A(t)=-.2 t^{2}+4 t+30$
(b) $A(t)=70-40 e^{.01 t}$
(c) $A(t)=30 \ln (t+1)$
(d) $A(t)=70-40 e^{-.06 t}$
