Question

Given the relation (3,0) (-2,-1) (0,-1) (-3,2) (3,2) Find the domain and range

Answer 1

ANSWER:

$\begin{gathered} D=\lbrace-3,-2,0,3\rbrace \\ R=\lbrace-1,0,2\rbrace \end{gathered}$

STEP-BY-STEP EXPLANATION:

We have that the domain are the input values of a function, that is, the values of x. In the case of the range, they are the output values, that is, the values of y.

Therefore, with the points given by the relation, the domain and the range would be:

$\begin{gathered} D=\mleft\lbrace3,-2,0,-3,3\mright\rbrace\rightarrow D=\mleft\lbrace-3,-2,0,3\mright\rbrace \\ R=\mleft\lbrace0,-1,-1,2,2\mright\rbrace\rightarrow R=\mleft\lbrace-1,0,2\mright\rbrace \end{gathered}$
