Careful! Be sure to check:
For a limit to exist, the limit from the left must agree with the limit from the right.
Recognize that this is Hana's Definition of the Derivative, and find f '(x), or use l'Hopital's Rule.
→(0 – 0), which is also an indeterminate form.
Before using l'Hopital's Rule, you will need to convert the argument into a single fraction that
To solve this limit, you will have to use l'Hopital's Rule twice.
then write the argument as a single fraction.
