As horizontal axis is x axis so it represents x.
we can see that x is between -1 and 3
-1<=x<=3
OpenStudy (neer2890):
any questions @SydtheKid913 ???

Thank you!
OpenStudy (neer2890):
what is 2nd option?
OpenStudy (sydthekid913):
O sorry I'll fix that
OpenStudy (sydthekid913):
there is supposed to be a 15 in front of the sign
OpenStudy (neer2890):
ok. now you can check whether the inequality holds for the value of x between -1 and 3
option 1 is incorrect as it does not hold for 0.
because for x=0
15<=3+9
15<=12 which is wrong.

@AndrewKaiser333
OpenStudy (andrewkaiser333):
since i was taught wrong i have to be sorry because i should have gotten a second person to help just in case
OpenStudy (neer2890):

both B and C satisfies for all the values of x between -1 and 3.
