Question

Suppose that the relation H is defined as follows.

H={(-5,0), (4,3), (-8,3)}
Give the domain and range of H.
Write your answers using set notation.
domain
=
range =
I
?

Answer 1

`Domain:= \{-5,4,-8\}`

`Range:=\{0,3\}`

Explanation:

Given

`H = \{(-5,0),(4,3),(-8,3)\}`

Required

The domain and the range

A function represented as:

`Function = \{(x_1,y_1),(x_2,y_2)......(x_n,y_n)\}`

Where:

`Domain=x_1,x_2,....,x_n`

`Range=y_1,y_2,....,y_n`

So:

`H = \{(-5,0),(4,3),(-8,3)\}`

`Domain:= \{-5,4,-8\}`

`Range:=\{0,3\}`
