When we talk about evaluating the limit of a function, we are looking at what happens to the function’s output as the input values get arbitrarily close to a certain point.

Mathematically, we denote the limit of a function f(x) as x approaches a specific value (let’s say a) using the notation:

lim(x->a) f(x)

The evaluation of the limit involves determining the behavior of f(x) as x gets closer and closer to a. There are several possibilities for the limit value:

1. The limit exists: If the value of f(x) approaches a particular number L as x approaches a, we say that the limit of f(x) as x approaches a exists and is equal to L. This is written as:

lim(x->a) f(x) = L

2. The limit does not exist: If the behavior of f(x) is not consistent as x approaches a, or if f(x) approaches different values from different directions, the limit is said to not exist.

3. Infinite limit: Sometimes, as x approaches a, the output of f(x) either increases or decreases without bound. In such cases, we say the limit is infinite, and we can denote it as:

lim(x->a) f(x) = ±∞

To evaluate the limit, we consider different techniques such as algebraic manipulation, substitution, factoring, L’Hôpital’s rule, or using known limit properties. It depends on the specific function and the behavior of its components.

Finally, it is important to note that evaluating a limit is not always straightforward, and some limits may require advanced calculus techniques or methods specific to certain functions or problems.
