Hello if someone could explain this question that would be great. Thanks.
guajiro [1.7K]

Answer:

Ok time to get math on

So this would be D

A non-filled in dot means < or > (depending where arrow is pointing)

A filled in dot means ≤ or ≥ (depending where arrow is pointing)

if an arrow points right, then it would be greater than, if arrow points left.. Then its less than

So the graph line is showing that it cannot be equal to AND it is lesser than so the only answer choice that would make the most sense is D

A is greater than which is not the answer

B is only equal to which is way off

C is less than but it is equal which is wrong

D is the only right answer

Hope this helps! :)
