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. Webhr. min. sec. SmartScore. out of 100.
