Definition:
An exponential function is a type of mathematical function where a variable (usually represented by "x") is in the exponent (the power). This means the function grows (or decreases) very quickly as the variable changes. The general form of an exponential function is written as ( f(x) = a \cdot b^x ), where: - ( a ) is a constant (a number that does not change), - ( b ) is the base (a positive number), - ( x ) is the variable in the exponent.
An exponential function is a special type of function that represents rapid growth or decay. It is frequently used in various fields to model real-world phenomena.
