Coober Pedy is a town in Australia that mines most of the world’s precious opals. Because of the scorching heat, much of the population lives in underground “dugouts.” The Coober Pedy monthly high temperatures are shown in Figure 1.116, with H(n) the temperature in month n, where n = 1 is January. We fit the data with a function,

(a) What does the value of C represent and what is its value?
(b) What does the value of A represent and what is its value?
(c) What is the value of B?
(d) Graph the data and the function.
