![Page 1: The right-hand limit of f (x), as x approaches a, equals L written: if we can make the value f (x) arbitrarily close to L by taking x to be sufficiently.](https://reader030.fdocuments.in/reader030/viewer/2022032701/56649c9d5503460f9495ca91/html5/thumbnails/1.jpg)
The right-hand limit of f (x), as x approaches a, equals L
written:
if we can make the value f (x) arbitrarily close to L by taking x to be sufficiently close to the right of a.
