lim x → a

Limit of Algebraic Function

Learn what the limit of an algebraic function means, study worked examples with graphs, then solve the questions step by step.

The limit of an algebraic function is the value that a function approaches as the variable x approaches a particular number.

The symbol for a limit is:

limx → a f(x)

Let’s understand each part.

lim

means limit.

x

is the variable.

x → a

means x approaches the number a.

f(x)

is the given function.

Example 1 of 5

Substitute the value of x step by step and find the limit of the function.
