The domain of the following relation {(1,2), (2,4),(-3,-6), (0,0)} can be express below
[tex]\begin{gathered} \text{The domain is the input value which is the x value.} \\ \text{domain}=\mleft\lbrace1,2,-3,0\mright\rbrace \end{gathered}[/tex]The range of the following relation {(1,2), (2,4), (-3,-6), (0,0)} can be express below
[tex]\begin{gathered} \text{The range is the output value which is the y value} \\ \text{range}=\mleft\lbrace2,4,-6,0\mright\rbrace \end{gathered}[/tex]The function below {(1,2), (2,4),(-3,-6), (0,0)) is a function because every function in x value has a corresponding y value.
