`f(x) = ln(x^2 - 2x)` Differentiate f and find the domain of f.
Differentiate `f(x)=ln(x^2-2x) ` and find the domain of f:
The domain is all possible inputs. The natural logarithm is defined for all inputs greater than 0, so `x^2-2x>0 ==> x<0,x>2 ` .
The derivative of `ln(u) ` is `(u')/u ` where u is a differentiable function of x.
