The following problems require the algebraic computation of limits of functions as x approaches plus or minus infinity. Most problems are average. A few are somewhat challenging. All of the solutions are given WITHOUT the use of L'Hopital's Rule. If you are going to try these problems before looking at the solutions, you can avoid common mistakes by giving careful consideration to the forms and during the computations of these limits. Initially, many students INCORRECTLY conclude that is equal to 1 , or that the limit does not exist, or is or . Many also conclude that is equal to 0 . In fact, the forms and are examples of
