The inverse of an exponential function.
Asymptote
The logarithm base b of a positive number x is defined as follows: logbx = y, if and only if x = b^y.
Natural Base Exponential Function
n an exponential growth function y = ab^x, with a > 0 and b > 1, the value b is the growth factor.

Logarithmic function
A logarithmic equation is an equation that includes a logarithm involving a variable.
Decay Function
A function with the general form y=ab^x, a ≠ 0, with b > 0, and b ≠ 1.

Logarithm
A natural logarithm function is a logarithm function with base e. The natural logarithm function, y = ln x, is y = loge x. It is the inverse of y = ex.
A line that a graph approches as x or y increases in absolute value.
The simplest example of a logarithmic function is the logarithmic parent function, written f(x) = logb(x), where b is a positive real number, b ≠ 1.
A natural base exponential function is an exponential functio with base e.
In an exponential decay function y=ab^x, with a > 0 and 0 < b < 1, the value b is the decay factor.
Natural logarithm function
Exponential Parent Functions
The exponential parent functions are functions of the form y = b^x, where x is a real number, b > 0, and b ≠ 1.
