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