Question

Suppose that the relation T is defined as follows.T = {(0,6), (2, -8), (-8, 2), (-3, -3)}What is the domain and range?

Answer 1

Given the follwing relation T:

`T=\mleft\lbrace(0,6\mright),(2,-8),(-8,2),(-3,-3)\}`

to write the domain, we have to gather all the first components of each ordered pair. In this case, the domain is:

`DomT=\mleft\lbrace0,2,-8,-3\mright\rbrace`

the range will be the second component of each ordered pair:

`Range(T)=\mleft\lbrace6,-8,2,-3\mright\rbrace`
