Chapter 2.5, Problem 85AYU
85. Thermostat Control Energy conservation experts estimate that homeowners can save to on winter heating bills by programming their thermostats 5 to 10 degrees lower while sleeping. In the graph (next page), the temperature T(in degrees Fahrenheit) of a home is given as a function of time (in hours after midnight) over a 24-hour period.
(a) At what temperature is the thermostat set during daytime hours? At what temperature is the thermostat set overnight?
(b) The homeowner reprograms the thermostat to . Explain how this affects the temperature in the house. Graph this new function.
(c) The homeowner reprograms the thermostat to . Explain how this affects the temperature in the house. Graph this new function.
