The graph illustrates home temperature, f(t), as a function of hours after midnight, t.

In Exercises 137–140, determine whether each statement makes sense or does not make sense, and explain your reasoning. If the statement makes sense, graph the new function on the domain [0, 24]. If the statement does not make sense, correct the function in the statement and graph the corrected function on the domain [0, 24].

I decided to keep the house 5° cooler than before, so I reprogrammed the thermostat to y = f(t) - 5.
