The domain is from -2 to 1 and the range is 3-6. The relation is a function. The mapping diagram is shown below.
Work Step by Step
The domain is from -2 to 1 because the x coordinates have values of -2,-1,0 and 1 and thus the relation has this domain. The range is from 3 to 6 because the y coordinates have values of 3,4, 5 and 6 and thus the relation has this range. The relation is a function because one x coordinate has only one y value and thus it passes the vertical line test.
