Question

List the domain and range of the relation. {(3. – 5), (7,7), (0, - 5), (7,1) (3,5)}

Answer 1

The domain of a list of points is all the x- values the function (or relation, they are the same words) can take.

In our case the domain is

`D=\mleft\lbrace3,0,7\mright\rbrace`

Similarly, the range of a list of points is all the possible y- values the relation can take; therefore, in our case the range is

`R=\mleft\lbrace-5,7,1,5\mright\rbrace`
