WebProving The Existence of Limits. Recall from the precise definition of a limit on the Introduction to Limits page, we said that the statement $\lim_{x \to a} f(x) = L$ says that for all $\epsilon > 0$ there exists a $\delta > 0$ such that if $0 < \mid x - a \mid < \delta$ then $\mid f(x) - L \mid < \epsilon$.We will now actually look at proving limits exist with the … WebWhen the limit exists, the definition of a limit and its basic properties are tools that can be used to compute it.

The function doesn't approach a finite value (see Basic Definition of Limit). The function doesn't approach a particular value …

WebWe cannot define limit as two values. You'll learn about the derivatives and you'll know that it's impossible to have two values. You'll have to find the slope of the tangent line at the certain point of x. And if the left limit and the right limit is different, there will be two slopes which are not possible. WebIn order for a limit to exist, both one-sided limits must be equal. Since finding one of the one-sided limits at the endpoint of a function is impossible, the limit as a function approaches an endpoint does not exist. In your example, however, the limit of f(x) as x approaches 5 from the negative side does exist (and equals 5). Hope this helps!
