Can you put up a picture of the graph? I think it would make it easier for me to understand ^.^
sure no problem
Ok Ima take a shot at it...
Domain is X so on the graph there's a point (-2, -1) So x would be -2
So of the choices, A or B could be the answer?
Since we narrowed it down we can look at the dots on the graph, -2,-1 point is "Open" while 3, 3 is "closed".
I think it should be A if you make a Quandaries and Queries chart...
Too clarify < or > is open and Less than greater than equal too is closed...
notice the -2 has a "hole" in it, thus is EXCLUDED from the domain, so "x" is never -2
−2 < x ≤ 3
so it is -2
−2 < x ≤ 3
so.. .whatever "x" is, or the domain we know that is NOT -2, but we know that, as it moves away from -2 and to 0, "x" is that and keeps on going till it gets to 3 bear in mind that, on the negative quadrants, the nuimbers closer to 0, are "bigger" thus -3 is really smaller than -2, because -2 is closer to 0 and -1 is bigger than -2 because -1 is closer to 0 so "x" is NOT -2, but bigger than that, and keeps on going till it gets to +3
domain= x is less than or equal to 3 and greater than -2.
Ok thanks. Can you help me with another problem?
why not, post!
ok hold on
