The term "e₂" typically refers to the mathematical constant e raised to the power of 2. The constant e is approximately equal to 2.71828 and is the base of natural logarithms. It is widely used in mathematics, particularly in calculus, to describe exponential growth and decay. In the context of functions, e² can represent exponential growth, where a quantity increases rapidly over time. This concept is applied in various fields, including finance, biology, and physics, to model processes such as population growth and compound interest.
