By definition, a function is a relation in which each input value has one and only one output value.
The input values are also known as x-values and the output values are also called y-values.
By definition, the Minimum is the lower point of the function.
Having the table shown in the exercise, you can identify the following points:
[tex]\begin{gathered} (-2,10) \\ (-1,8) \\ (0,6) \\ (1,4) \end{gathered}[/tex]
You can identify that the lower y-value of all those points is:
[tex]y=4[/tex]
Therefore, you can determine that the lower point of the function is:
[tex](1,4)[/tex]
The answer is:
[tex](1,4)[/tex]
