During the winter, you program your homethermostat so that at midnight, the temperature is 55. Thistemperature is maintained until 6 a.m. Then the house begins towarm up so that by 9 a.m. the temperature is 65. At 6 p.m. thehouse begins to cool. By 9 p.m., the temperature is again 55.Thegraph illustrates home temperature, f(t), as a function ofhours after midnight, t.In Exercises 137140, determine whether each statement makes senseor does not make sense, and explain your reasoning. If the statementmakes sense, graph the new function on the domain [0, 24]. If thestatement does not make sense, correct the function in the statementand graph the corrected function on the domain [0, 24].I decided to keep the house 5 cooler than before, so Ireprogrammed the thermostat to y = f(t) - 5.
