Question

How do you prove that the limit `x^(1/2) = 4` as x approaches 16 using the formal definition of a limit?

Answer 1

where the function is continuous, the limit is the actual value of the function

Explanation:

`lim_{x to 16} x^(1/2) = 16^(1/2)`

ie where the function is continuous, the limit is the actual value of the function
