Question 586821
<font face="Times New Roman" size="+2">


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 *[tex \LARGE +\infty] 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 *[tex \LARGE \ \ \leq\ \ ] or *[tex \LARGE \ \ \geq].  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 *[tex \LARGE x], if it is larger than 2, the wide end of the symbol goes toward the *[tex \LARGE x] and the pointy end goes toward the 2.  Otherwise it is the other way around. 


By the way, the plain text representations of *[tex \LARGE \ \ \leq\ \ ] and *[tex \LARGE \ \ \geq] are <= and >=.

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
