this one has been bugging me for a while now. we have just finished doing inequalities in class. here is an example of my problem:
y>-4 AND y<2
because AND is in there the way you would graph this would be to select all numbers between -4 and 2 because AND means that y has to qualify for BOTH inequalities for the statement to be true.
here is my problem:
y>-4 OR y<2
my math teacher says that in this case when graphing this the answers would be "all real numbers" but doesn't OR mean that it CANNOT qualify for both which means that y could equal any number lessthan -4 or any number greater than 2?
can someone PLEASE help me with this!?!?!?!
i love math but i dislike my math teacher to the extreme and would like nothing better than to prove her wrong!!!
