if the answer isFor Modulus questions , i get the two values of X which the questions asks ..
however when i try to write the inequality i dont get it !
is there any rule to write the inequalty because sometimes they give ranges as ans and sometimes ... or ,,,,
x<k or x>k+m
where k and m are constants and the purpose is that x is lesser than k and x is greater than a number greater than k. this is also a range.... just that it is n the extremes and not between 2 extremes.
if instead the inequalities are k<x<k+m then we get the thing that u are calling 'range' and this lies between the extremes.
furthermore, u decide the range by looking at ur answer.
e.g. if u are getting the answers:
x>k
x>m
(or any other answers really) just plot them on a numberline and see where they overlap. that will be ur answer. for further confirmation make sure to put a number from the answering range into the equation in the question to check if u were right. do check numbers by putting them into the equation to confirm that u have the correct range.
i hope that was not too confusing.
