Homework Statement
Find the Limit (as x-> -infinity) of [(7x^2)-x+11]/(4-x)
So I found that the limit is infinity/infinity indeterminate form so I tried to use L'hopital's to solve it.
So I took the derivative of (7x^2)-x+11 and got 14x-1
then for the derivative of 4-x I got -1
So the Limit as x->-infinity of 14x-1/-1 would be -infinity/-1 . So would the limit be infinity?
Apparently this answer is wrong. ...Is there a reason L'Hopital's wouldn't work here? How can I solve this?
Any help available would be much appreciated, thanks!
