1. The following is my logic for the answer I received: \sqrt{x} = x^{1/2} Using the power rule I bring the 1/2 out as a coefficient, and subtract one from the numerator : \frac{1}{2}x^{-1/2} I simplified to : \frac{-\sqrt{x}}{2} 2. My bad! I did a poor job transcribing it from my notebook...

For a function f(x), I have to determine intervals of increase/decrease, find local max(s)/min(s), and find intervals of concavity. The first thing I'm doing in this is to write out f'(x) and f''(x). f(x) = ln(x)/\sqrt{x} For f'(x), I used the quotient rule and received f'(x) =...
