We are given the graph of a line that takes values from 0 to 160 and outputs values from -1000 and 2200. We are asked to determine the domain and the range of the function.
The domain of a function is the values that the function takes as input and the range is the values that the function has as output.
Verbal description: the values that the function takes as input are the values from 0 to 160. If the values in the horizontal axis are "x", then the domain is
D = the values of "x" between 0 and 160
If the values in the vertical axis are "y", then the range is
R = the values of "y" between -1000 and 2200.
