Give the domain and range of G. Write your answers using set notation


Suppose that the relation is defined as follows.

{(5,5),(8,0),(6,-2),(-9,-8)}
Give the domain and range of G. Write your answers using set notation


G={(5,5),(8,0),(6,-2),(-9,-8)}
The domain is the set of x-coordinates and the range is the set of y-coordinates:

dom(G)={5,8,6,-9}
ran(G)={5,0,-2,-8}
