Determining if a Relation is a Function

Determining if a Relation is a Function 1.15 - Solution

arrow_back Return to Determining if a Relation is a Function

An ordered pair is a set of coordinates written in the form (x,y).(x,y). By rewriting the x-x\text{-} and y-valuesy\text{-values} from the table to match this form, we can identify the ordered pairs.

xx yy Ordered pair
55 -2\text{-} 2 (5,-2)(5,\text{-} 2)
99 88 (9,8)(9,8)
-1\text{-} 1 -7\text{-} 7 (-1,-7)(\text{-} 1,\text{-} 7)
88 -4\text{-} 4 (8,-4)(8,\text{-} 4)
