Which of the following must be equal to so that the limit exists at the point with x-coordinate 25?

 

f(25)

0

Nothing else. The one limit is sufficient. 

 

I thought option C.

\(\lim\limits_{ x \to 25^+ }f(x)\)  must be equal to \(\lim\limits_{ x \to 25^- }f(x)\)  so that the limit exists at the point with x-coordinate 25.
