What is the righthand limit of this function at x=2?
g(x)=x^2−3/x−3
A) 1
B) 0
C) 1
D) 2
E) 3

well, plug in x=2 and see what you get.

1 ?

Looks good to me.
When finding a limit, first try just plugging in the given value. As long as you don't wind up with 0/0 or something else undefined, the resulting value is the limit, as long as the function is not defined differently on the two sides.
