WebJan 24, 2016 · The typical graph of just ln(x) is graph{ln(x) [-10, 10, -5, 5]} Notice the domain restriction. In ln(x), x>0. That is, negative numbers are not in the domain of a logarithmic function. However, in ln(abs(x)), negative numbers are made positive. For example, both e^2 and -e^2, when plugged into ln(abs(x)), result in ln(e^2)=2. In effect, … Webf(x) = log e (x) Where e is "Eulers Number" = 2.718281828459... etc. But it is more common to write it this way: f(x) = ln(x) "ln" meaning "log, natural" So when you see ln(x), just remember it is the logarithmic function with …
