With this limit i don’t know what to do at all!

We're given

The function is continuous for all . If a function is continuous, then

This allows us to pass the limit through the square root:

The limit of a quotient is the quotient of limits (provided the limit of the denominator is not 0):

In the numerator, we can distribute the limit as

So we end up with

Then we just solve for the desired limit:

Obviously the limit can't have two values, so one of these is not right, but only the positive value is one of the answer choices, so the limit is 16.
