Question

Suppose that the relation S is defined as follows.s={(-2,8), (5.-9).(-9,0).(-6, -6)}Give the domain and range of S.Write your answers using set notation.Domain=Range=

Answer 1

Remember that

The Domain is the set of all the input values, which are the x-coordinate of each ordered pair (the first number in each pair).

The Range is the set of all output values, which are the y-coordinate of each ordered pair (the second number in each pair)

In this problem we have

s={(-2,8), (5.-9).(-9,0).(-6, -6)}

therefore

The domain is [-9,-6,-2,5]

The range is [-9,-6,0,8]
