(1 pt) Let f(x)=(-x^6)(lnx) . Find (a) the intervals on which f is increasing, (b) the intervals on which f is decreasing, (c) the open intervals on which f is concave up, (d) the open intervals on which f is concave down, and (e) the x-coordinates of all inflection points.
For the first derivative, I got the x value as e^(-1/6)
For the 2nd derivative, I got the x value as e^(-7/30)
Both those are apparently wrong. If you are able to help me out with the x values, I should be able to do the rest. Thanks!
