Exponential Function
An exponential function is formally defined as a mathematical function of the form , where the base is a constant such that and . Unlike linear or quadratic functions where the variable is the base, in an exponential function, the variable is the exponent. Exponential functions are essential for modeling many naturally occurring phenomena, including population growth, the spread of viruses, radioactive decay, and compounding interest.
