WebLet’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. Symbolically, we express this limit as. WebJan 2, 2024 · Evaluate the function at each input value. Record them in the table. Determine if the table values indicate a left-hand limit and a right-hand limit. If the left-hand and right-hand limits exist and are equal, there is a two-sided limit. Replace \(x\) with \(a\) to find the value of \(f(a)\).
