Evaluating Limits. "Evaluating" means to find the value of (think e-"value"-ating). In the example above we said the limit was 2 because it looked like it was going. 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. Sal finds the limit of (x²+x-6)/(x-2) at x=2 by factoring and simplifying the expression.
