Question

A research scientist measures the outside temperature, in degrees Fahrenheit, at various
times throughout a 24-hour period and records her findings in the graph below. In this
real-world function, the hours represent the input values, and the temperature represents
the output values. Use the graph to identify the range of the function. Write your answer
as a set of ordered pairs. Then write a sentence to explain what the range represents in
this function.

I did the table and I can't remember how to get the range.
FRom 2-7= the temperature rose 15+
from 7-12= the temperature rose 5+
from 12-18= the temperature lowered 10-
from 18-22= the temperature lowered 15-
the range are the numbers on the right which would be in this order from
2 pm:65
7pm:80
12pm:85
18:75
22:60

How do I find the range?

Answer 1
