What is a function?
A function is a relation between two sets of values, an input and an output value given as X and Y respectively, in which each input value of X has exactly one output value for Y.
An example of a function is y = x^2 + 1.
If x = 1
Then;
y = 1^2 + 1
y = 2
The input of a function is called the domain.
The output of a function is called the range.
Since the table provided is not clear, any of such table where an input value of X gives exactly one output value of Y is a function.
