Question

Determine the domain and range of the graph? Remember that repeated values in a set only need to be included once.

Answer 1

Given:

The graph has points plotted as:

`A(6,-3),B(3,-2),C(6,0),D(0,-7)`

The domain is the set of x-values plotted on graph forwhich the function is defined.

Here the domain is:

`=\mleft\lbrace0,3,6\mright\rbrace`

The range is the set of y-values plotted on graph.

Hence, the range is:

`=\mleft\lbrace-7,-3,-2,0\mright\rbrace`
