Exponential functions are mathematical expressions in the form of $$f(t) = a e^{kt}$$, where 'a' is a constant, 'e' is the base of the natural logarithm, 'k' is a constant that represents growth (if positive) or decay (if negative), and 't' is the variable. These functions are essential in various applications, especially in describing processes that involve growth or decay, such as population dynamics and radioactive decay. Their unique properties, such as rapid increase or decrease, make them particularly useful when analyzing systems over time.
