The logarithm function. If you specifically mean the function ex, the inverse function is the natural logarithm. However, functions with bases other than "e" might also be called exponential functions.
"The" exponential function is ex. A more general exponential function is any function of the form AeBx, for any non-xero constants "A" and "B". Alternately, Any function of the form CDx (for constants "C" and "D") would also be considered an exponential function. You can change from one form to the other.
With exponentiation functions, the rate of change of the function is proportional to it present value.A function f(x) = ax is an exponentiation function [a is a constant with respect to x]Two common exponentiation functions are 10x and ex. The number 'e' is a special number, where the rate of change is equal to the value (not just proportional). When the number e is used, then it is called the exponential function.See related links.
The presence of any term that is not a constant or a multiple of the independent variable. It can be any other power of that variable, or a trigonometric or exponential or any other function.
Basically, a rational expression would include only additions, subtractions, multiplications, divisions, and integer powers, while an irrational expression could, in addition, include several additional functions, such as roots (or equivalently, non-integer powers), exponential functions, logarithms, trigonometric functions, and just about any other function.

If y is an exponential function of x then x is a logarithmic function of y - so to change from an exponential function to a logarithmic function, change the subject of the function from one variable to the other.
Exponential and logarithmic functions are inverses of each other.
An exponential function is any function of the form AeBx, where A and B can be any constant, and "e" is approximately 2.718. Such a function can also be written in the form ACx, where "C" is some other constant, used as the base instead of the number "e".
Exponential and logarithmic functions are different in so far as each is interchangeable with the other depending on how the numbers in a problem are expressed. It is simple to translate exponential equations into logarithmic functions with the aid of certain principles.
The exponential function - if it has a positive exponent - will grow quickly towards positive values of "x". Actually, for small coefficients, it may also grow slowly at first, but it will grow all the time. At first sight, such a function can easily be confused with other growing (and quickly-growing) functions, such as a power function.

The exponential function is e to the power x, where "x" is the variable, and "e" is approximately 2.718. (Instead of "e", some other number, greater than 1, may also be used - this might still be considered "an" exponential function.) The logarithmic function is the inverse function (the inverse of the exponential function).The exponential function, is the power function. In its simplest form, m^x is 1 (NOT x) multiplied by m x times. That is m^x = m*m*m*...*m where there are x lots of m.m is the base and x is the exponent (or power or index). The laws of indices allow the definition to be extended to negative, rational, irrational and even complex values for both m and x.There is a special value of m, the Euler number, e, which is a transcendental number which is approx 2.71828... [e is to calculus what pi is to geometry]. Although all functions of the form y = m^x are exponential functions, "the" exponential function is y = e^x.Finally, if y = e^x then x = ln(y): so x is the natural logarithm of y to the base e. As with the exponential functions, the logarithmic function function can have any positive base, but e and 10 are the commonly used one. Log(x), without any qualifying feature, is used to represent log to the base 10 while logx where is a suffixed number, is log to the base b.
anything raised to the power of x, f(x) = 2^x and f(x) = e^x are common examples. The exponential function, f(x)=e^x is the most important function in mathematics. One of the most important properties of the exponential function is: f ( X + Y ) = f (X) * f (Y) It is defined as Exp(X) = 1 + X + X^2/2! + X^3/3! + . . . exponential functions of other bases can be defined as follows: B^X = Exp (XlogB) where log is the inverse of Exp.
