Question

Given the set of ordered pairs {(2,5), (5,2),(-2,2)}, how do you determine the domain and range?

Answer 1

The domain is the set of first value, the range is the set of second value.

Explanation:

For the set of ordered pairs {(2,5), (5,2),(-2,2)},

The Domain is: `{2,5,-2}`
(Which may also be written: `{-2,2,5}` if you want to put the numbers in order.)

The range is: `{5,2}`
(This is the same as `{5,2,2}`.

A set is completely determined by what is in it, regardless of the order or number of times it is written down.
