A non-linear function is a function that does not have a constant rate
For a function to be non-linear, then the table of the function must show that the function values change at irregular rates.
The tables are not given. So, I will make use of the following tables to justify my point.
Take for instance
Table A Table B
x y x y
0 0 0 5
1 2 1 9
2 4 2 4
In table A, as the x values increases by 1, the y values increase by 2 (this represents a linear function)
In table B, as the x values increases by 1, the y values increase at different intervals (this represents a nonlinear function)
