This problem is on a test that our teacher said we could research if we wanted...and we are finishing it tomorrow. I have NO CLUE how to approach it and need help!

1. The problem statement, all variables and given/known data

lim x->infinity [tex]

x - ln(1+2e^x)

[/tex]

2. Relevant equations

3. The attempt at a solution

so, its infinity - infinity, which is indeterminate.

I did the limit function on my TI-89, and it just keeps spitting the original equation back at me as the answer. I then graphed the function on my TI-89, and when it goes past x=2302, the graph is undefined. HOWEVER, when i go into the table, the values after 2302 go to -infinity, so I think thats what the answer's supposed to be...but I have no idea how to set up the quotient and solve using L'Hospital's Rule...PLEASE HELP!!!
