Question

What is the range of the relation (-2,3) (0,3) (2,5) (2,9)

Answer 1

The range of a relation is given by the values of y the relation can assume.

Looking at the ordered pairs in the relation, the y-values that can be assumed are 3, 5 and 9.

Therefore the range is:

`range=\mleft\lbrace3,5,9\mright\rbrace`
