What are nonlinear graph?

Nonlinear graphs represent relationships between variables that do not follow a straight line. Instead, the data points may form curves or other complex shapes, indicating that changes in one variable do not produce proportional changes in another. Common examples include quadratic, exponential, and logarithmic functions, which are used to model various phenomena in fields like physics, Biology, and economics. Nonlinear graphs highlight the intricate dynamics and interactions within the data, making them essential for understanding complex systems.
