Question

what is a nonlinear function

Answer 1

A nonlinear function is a mathematical function that does not follow a straight line when graphed. In other words, it does not have a constant rate of change. Nonlinear functions can take various forms, such as quadratic, exponential, logarithmic, and trigonometric functions, among others. These functions can have curves, bends, and other irregular shapes when visualized on a graph.
