the limit as x--> - infinity of √(4x²-1)/ 7 - lxl
I don't understand how to treat absolute value of x in the denominator.
I assume this would be indetirminate as you end up with neg inf./inf
so I would have to take the derivitive (l'hospital's rule) of the top and bottom
the top would become 4x ( 4x²-1) to the -1/2 power
the bottom would become X+1/ lxl??
I'm really unsure and I feel like this may not exist.
Thanks for all your help, you guys are great!!!!!!!!!!!!
(ps. no calc. question)
