Question

Suppose that the relation G is defined as follows. G={(4, -4), (-6,0), (-6, -7), (-1, 4)}Give the domain and range of G. Write your answers using set notation.

Answer 1

Let's draw a Venn diagram of the given relation:

The domain is the set of all first elements of ordered pairs (x-coordinates) and the range is the set of all second elements (y -coordinates).

Therefore, from the picture above, the answer is:

$\begin{gathered} \text{DOMAIN: }\mleft\lbrace-6,-1,4\mright\rbrace \\ \text{RANGE:}\mleft\lbrace-4,0,4,7\mright\rbrace \end{gathered}$
