Exponential function in mathematics a relation of the form y ax with the independent variable x ranging over the entire real number line as the exponent of a positive number a. F x b k x. K rate of growth when 0 or decay when.
An exponential function is a mathematical expression in which a variable represents the exponent of an expression.
