3.3 The logarithm as an inverse function - Sam Houston State University

3.3.1 The meaning of the logarithm The logarithmic function g(x) = log b (x) is the inverse of an exponential function f(x) = bx:and so the meaning of y= log b (x) is by = x:The expression by = xis said to be the \exponential form" for the logarithm y= log b (x). The positive constant bis called the base (of the logarithm.) Some worked exercises. ................
