Answer 1

Step 1

A function is one in which each element in the domain has a unique value

Hence where G represents a graph,

`\begin{gathered} G_1is\text{ not a function } \\ G_1=No \end{gathered}`
`\begin{gathered} G_{2\text{ }}is\text{ not a function} \\ G_2=No \end{gathered}`
`\begin{gathered} G_3=\text{ No} \\ G_3\text{ is not a function} \end{gathered}`
`\begin{gathered} G_4=Yes \\ G_4\text{ is a function} \end{gathered}`
`\begin{gathered} G_5=Yes \\ G_5_{}isafunction_{} \end{gathered}`
`\begin{gathered} G_{6\text{ }}=\text{ No} \\ G_6\text{ is not a function} \end{gathered}`
