A can of soda is placed inside a cooler. As the soda cools, its temperature T(x) in degrees Celsius is given by the following exponential function, where is the number of minutes since the can was placed in the cooler.
T(x)=-22+44e^-0.03x

Find the initial temperature of the soda and its temperature after 18 minutes. Round your answers to the nearest degree as necessary.

1. T(x) = -22 + 44*e^(-0.03x).

T(o) = -22 + 44*e^(-0.03*0),
T(o) = -22 + 44*e^0 = -22 + 44*1 = 22deg C.

T(18) = -22 + 44*e^(-0.03*18),
T(18) = -22 + 44*0.5827 = 4 deg C.
