Limits Math Help

Definition of LimitReturn to Top

The limit is a method of evaluating an expression as an argument approaches a value. This value can be any point on the number line and often limits are evaluated as an argument approaches infinity or minus infinity. The following expression states that as x approaches the value c the function approaches the value L.

Right Hand LimitReturn to Top

The following expression states that as x approaches the value c and x > c the function approaches the value L.

$right hand limit definition$

Left Hand LimitReturn to Top

The following expression states that as x approaches the value c and x < c the function approaches the value L.

Limit at InfinityReturn to Top

The following expression states that as x approaches infinity, the value c is a very large and positive number, the function approaches the value L.

$limit at infinity$

Also the limit as x approaches negative infinity, the value of c is a very large and negative number, is expressed below.
