What is a Nonlinear Function? A nonlinear function is a function whose graph is NOT a straight line. Its graph can be any curve other than a straight line.

Learn about non linear functions with simple definitions, key equations, and graph explanations. Explore solved examples to understand how non-linear functions work in math.

The graph of a linear function is a straight line. The graph of a nonlinear function is a curved line. There are many different types of nonlinear functions.

Sep 4, 2025 · Nonlinear functions are visually represented by graphs that are not straight lines. These graphs can take various shapes, such as curves, parabolas, or hyperbolas, reflecting the non …

In simpler terms, it's any function where the output does not change at a constant rate when the input changes at a constant rate. In other words, the graph of a nonlinear function is not a straight line.

From the graph, we can say that the slope is not uniform on a nonlinear function. A nonlinear function can be described using a table of values, an equation, or a graph.

One way to determine if a function is linear or non-linear is by inspecting the rate of change using a table of values or by examining its graph. Functions described by non-linear equations do not have a …

Unlike linear functions, the rate of change in nonlinear functions is not constant but variable. Because of that, the graphs of nonlinear functions follow curved lines.
