Help with this question, please.

The limit of any constant function is the value of the constant, so the limit is just 5.
For this case we have that by definition:
The limit of a constant function of the form [tex]y = f (x)[/tex], where [tex]f (x) = c[/tex], is the same constant, whatever the value to which the limit tends.
Thus, the limit of "5" when x tends to "2", results in "5".
Answer:
5
Option A
