I'm trying to figure out whether a particular relationship or trend in my data is linear or not. I'm looking for ways to identify if the pattern follows a straight line or if it's more complex.

Determining whether a function is linear or nonlinear can be achieved by examining its graphical representation.

A linear function, when plotted on a graph, creates a straight line. This is a defining characteristic of linearity.

The straight-line graph indicates that the rate of change of the function is constant, meaning the slope remains the same throughout.

Conversely, a nonlinear function does not form a straight line when graphed.

Instead, a nonlinear function exhibits curvature, indicating that the rate of change varies across the function.
