Answer the Essential Question: How can function models help us make predictions?

The temperature at the beach varies throughout the day. The temperatures vary according to the sinusoidal function:

A(t)= 19+6sin (\pi (t - \dfrac{1}{2}))

where t is the temperature (ºC) and A(t) is the time in hours past midnight.

The temperature in the desert is modeled by the function B(t)=\dfrac{35t(t-5)}{t^2+8t+16} + 17, where t is the temperature (°𝐶) and A(t) is the time in hours past midnight.
