How to solve rational limits
WebMIT grad shows how to find the limit as x approaches infinity or negative infinity. To skip ahead: 1) For a POLYNOMIAL or CONSTANT in the limit expression, skip to 1:56. 2) For a RATIONAL... WebJul 9, 2024 · The first technique for algebraically solving for a limit is to plug the number that x is approaching into the function. If you get an undefined value (0 in the denominator), you must move on to another technique. But if your function is continuous at that x value, you will get a value, and you're done; you've found your limit!

WebNov 10, 2024 · Limits of Polynomial and Rational Functions Let p(x) and q(x) be polynomial functions. Let a be a real number. Then, lim x → ap(x) = p(a) lim x → ap(x) q(x) = p(a) q(a) when q(a) ≠ 0. To see that this theorem holds, consider the polynomial p(x) = cnxn + cn − 1xn − 1 + ⋯ + c1x + c0.

WebNov 28, 2024 · Using direct substitution to find the limit results in the indeterminate form 00. In order to evaluate the limit, we need to transform the expression to remove the indeterminate form. This is accomplished by using the relationship for the difference of squares of real numbers: x2−y2=(x+y)(x−y). WebTo find this limit, let’s start by graphing it. Use your graphing calculator.

The limit may or may not exist. For example: lim x-->0 of (x/x) = lim x-->0 of 1 = 1, but lim x-->0 of [x/ (x^2)] = lim x-->0 of (1/x) = 1/0 = +-infinity, so this limit does not exist.
