If function is given by its table representation and you have to determine what type of function it is, you can’t be 100% sure that the given function is linear. Why is that so? Because there are many functions which have the same table representation.
Example: You’re given f(0)=0 and f(1)=1. It can be representation of function f(x)=x, f(x)=x^2, f(x)=x^3 etc. If there are more given datas, maybe you can eliminate some types of functions, but you can’t be sure what type of function it is. :)

a linear function is used to relate to relate an independent variable and a dependent variable by introducing a rate of change(function) of which the independent variable is equated to find the dependent variable for example y=3x hence hence is the dependent variable as it depends on the change of x and 3 is the rate of change which is a constant and is determined by the division of the values of y/x hence to make a table of y over x of which y is determined by the rate of change 3*the independent variable x
