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