What is a non linear function
A nonlinear function is a mathematical function that does not have a linear relationship between its input and output variables.
The rate of change of the output with respect to the input is not constant. Unlike linear functions, which form straight lines when graphed, nonlinear functions can exhibit more complex and curved patterns.
Nonlinear relation that is not a function means that for at least one input, there are multiple corresponding outputs.
