Question

Please help me with this. I don’t know how to do it

Answer 1

Given:

`\lbrace(1,2)(5,8)(9,-4)\rbrace`

If the function represent in from:

`\begin{gathered} \lbrace(a,b)(c,d)\rbrace \\ \text{Range}=\lbrace b,d\rbrace \\ \text{Domain}=\lbrace a,c\rbrace \end{gathered}`

so range is:

`\lbrace-4,2,8\rbrace`
