If x is approaching The through values greater than The or on your right we write:
This limit is called the lateral boundary on the right in The.
If x approaches a through values less than The or on your left we write:
This limit is called the left side boundary in The.
The limit of f (x) for xa exists if and only if the right-to-left side boundaries are equal, or are:
We say that a function f (x) is continuous at one point The your domain if the following conditions are met:
Property of Continuous Functions
If f (x) and g (x) are continuous in x = The, then:
f (x)g (x) is continuous in The;
f (x). g (x) is continuous in The;
is continuous in The .
