1. ## Two calc questions...stumped

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 $f(x) = \ln{x}$?

If so, $f'(x) = \frac{1}{x}$, therefore $f'(2) = \frac{1}{2}$.

For part two, the correct answer is $-\frac{1}{x^2}$.
