Average daily high temperatures in Ottawa, Canada range from a low of –6 degrees Celsisus on January 1 to a high of 26 degrees Celsius on July 1 (six months later). Let H(t) be the function describing Ottawa's average daily high temperature (where t = 0 on January 1). Use the information above to find the period, amplitude, equilibrium, and midline of H(t). You do not need to sketch a graph of H(t), but you may find it helpful to do so.
