Is it important to know the domain of a logarithmic function before finding the derivative? Why?

Solutions

Expert Solution

To make sure that the derivative of the logarithmic function is well defined, It is important to know the domain of the function. Let us take an example, Let F(x)= x/[1-ln (x-1)]

The step by step explanatory solution is provided below.
