The temperature at 6:00 A.M. was 58° Fahrenheit. The temperature increased at a constant rate of 3° Fahrenheit every hour until 10:00 A.M. The equation below models t as a function of h where 1 is the temperature and h is the number of hours.
t = 58 + 3h
Which set represents the range of this function?
we know that
the range, represent the possible values of y
in this problem, the range represent possible values of temperature
so
the range of the temperature is
For h=0
t=58
For h=4 hours (1000-600)
t=58+3(4)=70
the range is the interval [58,70]
