Which of the following equations is represented by the graph below

This is one question I'm having problems with. I'm not good with the inequalities and such. =\

Here's the graph:

--------------------------------------…
-3 -2 -1 0 1 2 3 4 5 6 7

typed it as best as I could, where the positive 3 is is where it's supposed to have the circle filled in above it, and the arrow on the number line moves from the 3 up to the 6, now which one of these equations represent it?
1: g > 3
2: g (the less than or equal to sign) 3
3: g (the more than or equal to sign) 3

Thanks in advance. (:

g is greater than or equal to three.
