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:
You can identify that the lower y-value of all those points is:
Therefore, you can determine that the lower point of the function is:
The answer is:
