whats it is laying on? x-axis

OpenStudy (mathmale):

first of all, the domain is connected with x-coordinates and the range with y-coordinates. Here the domain is the set of all INPUT values (all x-values) that are shown on the graph. You'll need to decide whether or not the domain includes or does not include 1 or 5.

OpenStudy (alexandervonhumboldt2):

waitwaitwaitwait. this is a test isn't it?

OpenStudy (mathmale):

Take a good, hard look at the x-asix in the given diagram. Which x values are represented by graphs and whihc are not.

OpenStudy (boldjon):

k so what do the darkened and non darkened circle mean mean

OpenStudy (boldjon):

i just get it

OpenStudy (boldjon):

don't get it

OpenStudy (mathmale):

If you choose an x value for which there is a graph, great. that x value is part of the domain. If, on the other hand, you choose an x-value for which there's no corresponding graph, that x value is NOT part of the domain.

OpenStudy (beautifulmystery.):

inequality's

OpenStudy (boldjon):

so b?

OpenStudy (boldjon):

since it's 1 and 5

OpenStudy (mathmale):

for example, PART of the domain of the illustrated function is [3,5): It includes 3 and all x vaues up to but not including 5.

OpenStudy (boldjon):

oh ok

OpenStudy (mathmale):

a and b are very close, but are not the same. I need to know how y ou decide which one is the correct answer.

OpenStudy (boldjon):

becuz in B they both have less than equal signs

OpenStudy (boldjon):

i mean lesser than or equal to signs

OpenStudy (mathmale):

My last statement contains all the info y ou need to choose the correct answer. Hint: Look at the very end, the right end, of your interval.

OpenStudy (boldjon):

oh it's A

OpenStudy (mathmale):

Look at the end of the graph that is furthest to the right. Do you see a circle there, or a dot? That makes a big difference.

OpenStudy (mathmale):

Yes, it is A.

OpenStudy (boldjon):

lol thanks a lot
