The Natural Exponential Function

The Natural Exponential Function. Definition. The inverse function of the natural logarithmic function f(x) = ln x is called the natural exponential function and is denoted by f -1 (x) = e x y = e x if and only if x = ln y ln (e x ) = x e lnx = x.

  1. The Natural Exponential Function

  2. Definition The inverse function of the natural logarithmic function f(x) = ln x is called the natural exponential function and is denoted by f-1(x) = ex y = ex if and only if x = ln y ln(ex) = x elnx = x

  3. Properties of Natural Exponential Functions The domain of f(x) = ex is (-∞, ∞) and the range is (0, ∞) The function is continuous, increasing, and one-to-one on its entire domain The graph is concave upward on its entire domain and
