A logarithmic function is not the inverse of an exponential function.
The base of a logarithmic function can be a negative number.
The domain of the logarithmic function f(x) = log2x is all real numbers.
The range of the logarithmic function f(x) = log2x is all real numbers.

Answer 1

hint... don't base on the negatives.
ln e^x = x
stay in the positive domain
