Question

Scientists sometimes use the formulaf (t) =a sin (bt + c) + d to simulate temperature variations during the day, with
time t in hours, temperature f (t) in C, and t = 0 corresponding to midnight. Assume that f (t) is decreasing at midnight.
(a) Determine values of a, b, c, and d that fit the information. ,(b) Sketch the graph of f for 0 < t <24. 

The temperature at midnight is 15°C, and the high and low
temperatures are 20°C and 10°C.
