You are correct. If you look on the chart, -1 in the y - axis right next to 2 in the x-axis. When you look at the table 0 is right by the 3 and 1 is right by the one but when you look at the last two numbers on the chart which are -1 and 2 those numbers are right next to each other. The question asks you, using the table, what is the value for the <u>range</u> when the <u>domain</u> is 2? When looking at the chart you can easily tell what the value is for the range, it´s -1. The y- axis and the x-axis are listed with numbers across from each other. For instance 0 (x-axis) and 3 (y-axis are right accross from each other, 1 (x) and 1 (y) are right across from each other and 2 (x) -1 (y) are right across from each other. So when you look at the last 2 number of the x and y - axis you can automatically see that -1 is the range of 2
Linear. While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value).
