Hey guys!

We've spent the last 5 classes using derivatives to study to graphically represent functions, but there are some functions which seem to give you a headache.

for example :

i found where the function is defined ( ),

i found the asimptotes ( it has only a vertical one at ) , but when I have to find monotony and extreme values I get stuck.

First I find the first derivative, then I have to make it equal to zero and then I'm left with . how do I find x from here?

It sounds silly, but i'm kinda stuck.

Regards,

Rinor
