1) What is the slope of f(x) = In x, at x = 2? 2) Find f''(x) of f(x) = In x -I know this one must be either 1/x or -1 / x^2 Thanks!!

Is that $\displaystyle f(x) = \ln{x}$? If so, $\displaystyle f'(x) = \frac{1}{x}$, therefore $\displaystyle f'(2) = \frac{1}{2}$. For part two, the correct answer is $\displaystyle -\frac{1}{x^2}$.
