I have to find where y is increasing/decreasing, where it's concave up/down and any inflection points, if there are horizontal asymptotes, and then sketch it. Here's the problem:
y = x^k/1+x^k
k is a positive integer greater than one. Here's what I get for the first derivative, after that I'm stuck:
My guess is that the function is increasing for x>o and decreasing for x<0 but stuck after that.
