1. LEQ: What is the process used to evaluate expressions containing the natural logarithm?

2.  Logarithms to the base e  Written ln x (or log e x)  Definition: n = ln m, the natural logarithm of m, if and only if m = e n  Example: ln e 4 = 4 ln 10 ≈ 2.30

3.  f(x) = ln x  Is the inverse of g(x) = e x  Graph:  Domain: the set of positive real numbers  Range: the set of all real numbers  x-intercept is 1, no y-intercept  The y-axis (x = 0) is an asymptote to the curve
