Question

Suppose that the relation G is defined as follows.

G={(7, d), (1, a), (8,8), (d, 0);
Give the domain and range of G.
Write your answers using set notation.
domain =
0,0....
Х
range

Answer 1

`Domain = \{7,1,8,d\}`

`Range = \{d,a,8,0\}`

Explanation:

Given

`G=\{(7, d), (1, a), (8,8), (d, 0)\}`

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:

`G=\{(7, d), (1, a), (8,8), (d, 0)\}`

`Domain = \{7,1,8,d\}`

`Range = \{d,a,8,0\}`
