WebSep 24, 2015 · A limit doesn't exist if the function is not continuous at that point. The way to find out if a limit of a certain function exists or not is to approach the limit from the left and the right side. For example: Take the limit of the function f (x) as x approaches 0. WebIntuitive Definition of a Limit. Let’s first take a closer look at how the function f(x) = (x2 − 4) / (x − 2) behaves around x = 2 in Figure 2.2.1. As the values of x approach 2 from either side of 2, the values of y = f(x) approach 4. Mathematically, we say that the limit of f(x) as x approaches 2 is 4.

WebActually, if you take 1/ x-2 , the limit is infinity, therefore the limit does NOT exist. Think of lim = infinity as a special case of the limit not existing. Consider this intentionally absurd statement (from W. Michael Kelley's Humongous Book of Calculus Problems): "the limit is that it's infinitely unlimited". Yeah, makes no sense. WebAccording to some presentations of limits, it is proper to write " lim x → 0 1 x 2 = ∞ ." This does not commit one to the existence of an object called ∞. The sentence is just an abbreviation for "given any real number M, there is a real number δ (which will depend on M) such that 1 x 2 > M for all x such that 0 < x < δ ."
