Notation

In formulas, a limit of a function is usually written as

and is read as "the limit of f of x as x approaches c equals L ". This means that the value of the function f can be made arbitrarily close to L, by choosing x sufficiently close to c. Alternatively, the fact that a function f approaches the limit L as x approaches c is sometimes denoted by a right arrow (→ or → {\displaystyle \rightarrow }), as in

which reads " f {\displaystyle f} of x {\displaystyle x} tends to L {\displaystyle L} as x {\displaystyle x} tends to c {\displaystyle c} ".
