The following problems require the use of the algebraic computation of limits of functions as x approaches a constant.
Most problems are average.
A few are somewhat challenging. If you are going to try these problems before looking at the solutions, you can avoid common mistakes by giving careful consideration to the form during the computations of these limits. In fact, the form is an example of an indeterminate form. This simply means that you have not yet determined an answer. Usually, this indeterminate form can be circumvented by using algebraic manipulation.
