WebMar 3, 2024 · If ‘a’ is any number such that a>0 and a≠1, then the exponential function formula is: f (x) = ax. Where the variable x occurs as an exponent. It is a real number. If x is negative, the function is undefined for -1 < x < 1. The following exponential function examples explain how the value of base ‘a’ affects the equation.
