I surmise you meant "arrow" instead of "aero" I'm also guessing that answers A and D are not actually the same nor are B and C.

The arrow actually starts either exactly at 2 (if there is a solid dot on the 2) or at any amount however small larger than 2 (if there is an open circle on the 2). The arrow actually points to

meaning that the set of values goes on forever in the positive direction.

If you have a solid dot on the 2, then the relation is inclusive, meaning the number 2 is actually included in the described set of values and the relationship indicator must be inclusive of equals, i.e. either

. Then you have to decide which way the symbol points. The pointy end of the symbol always points to the smaller quantity. Pick a spot on the arrow that is NOT the end point 2. Is the number you picked larger or smaller than 2? Since the spot you picked is a possible value for

, if it is larger than 2, the wide end of the symbol goes toward the

and the pointy end goes toward the 2. Otherwise it is the other way around.

By the way, the plain text representations of

and

are <= and >=.
