Over a 24-hour period, the temperature in a town can be modeled by one period of a sinusoidal function. The temperature measures 70F in the morning, rises to a high of 80F, falls to a low of 60F, and then rises to 70F by the next morning. What is the equation for the sine function f(x), where x represents time in hours since the beginning of the 24-hour period, that models the situation? Enter your answer in the box. f(x) =
