Derivatives/Graphing issues

Hi guys. I'm having trouble going through these practice problems that we've just started in Calc A. Any help would be greatly appreciated :)

The objective is to find the

a) relative maximums

b) relative minimums

c) points of inflection

d) increasing interval

e) decreasing interval

f) concave up in the interval

g) concave down in the interval

and

h)asymptotes, if they exist

This is all after finding the first and second derivatives for:

1.

2.

and

3.

I literally could only find the derivatives for the first equation. I am having a really tough time with this and any help is greatly appreciated :) Thanks
