WebJul 30, 2024 · Intuitive 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.

WebNov 16, 2024 · If we can find two paths upon which the function approaches different values as we get near the point then we will know that the limit doesn’t exist. Let’s take a look at a couple of examples. Example 1 Determine if the following limits exist or not. If they do exist give the value of the limit. 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.
