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?
I found it: the range is the output, smallest to biggest
To find the range of a function, you need to consider the output values (in this case, the temperatures) recorded in the graph. Since you have already identified the temperatures at different times, you can simply write down the set of ordered pairs as follows:
{(2, 65), (7, 80), (12, 85), (18, 75), (22, 60)}
In this context, the range represents the set of all possible temperatures recorded throughout the 24-hour period. It shows the lowest and highest temperatures captured during that time.
