Question
The thermostat in an empty apartment is set to 65° F from 4:00 a.m. to 5:00 p.m. and to 50°F from 5:00 p.m. until 4:00 a.m. Here is a graph of the function H that gives the temperature I (x) in degrees Fahrenheit in the apartment x hours after midnight.
The thermostat in an empty apartment is set to 65°F from 4:00 a.m. to 5:00 p.m. and to 50°F
from 5:00 p.m. until 4:00 a.m. Here is a graph of the function H that gives the temperature H(x)
in degrees Fahrenheit in the apartment x hours after midnight.

1. The owner of the apartment decides to change to a new schedule and they set the thermostat
to change 3 hours later in the morning and the evening. On the same axes, sketch a graph of
the new function, G, giving the temperature as a function of time.
