Note for OP
+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.okay what have you tried so far
@Abhi what class are you in?
I need to know so I can explain it to you in the required terminology
If that makes sense
Class 11
Alright so
What do you understand from this question
Send the image you posted bruh
ghost ping?
Nah posted a image was editing that
Seems correct to me
What's the problem?
As x belongs to R put x=5 in Inequality it doesn't satisfy the inequality
Nevermind I mixed the sign up 💀
You're supposed to use the region that satisfies both conditions here, which is x= [2,4]
So while solving modulus inequality I noticed that in some cases we take union of results of all cases while in some case we take intersection of results of all cases. Why though ?
so case 1, you already considered x is greater than or equal to 3 and then you got the set of all real numbers that are less than or ual to 4 but since x should also be greater than 3, the values of x that satisfy the inequality according to case 1 should lie between 3 and 4 {[3,4]}
similarly in case 2, you already considered x to be less than 3 and then got the set of all real numbers greater than or equal to 2 so the values of x satisfying the inequality according to case 2 are [2,3)
oh so now if we take union the answer will come [2,4]
bro clearly x is less than equal to 4 but greater than equal to 2 , how does x belong to R?
I took union of case 1 and 2
don't know why thought its my confusion
true, take intersection, not union @Abhi
yeah
jaha bhi AND aaye that means intersection OR matlab union
No.
Union hi lena hai
Bhai ne regions properly define nahi kare
T_T intersection?
arey bhai mod kholne par 2 cases bante na dono ko satisfy karne ke liye wo values of x loge na jo common ho
intersection hi lena padega wtf 😠am i saying dumb things?
no
When x ≥ 3 fir correct region should be x= [3,4]
When x<3 correct region should be x = [2,3]
Take union of both you get [2,4]
@lmaodedXD try to take intersection in this ques
@lmaodedXD gadho waali baate mat Kiya kr
,rotate
,rotate
Mere Bhai initial condition to laga le ðŸ˜
?? sab toh lagaya hai kya keh rha
Aadha adhura solve karke galat bata rha usko
intersection hii toh hoga , union kaise
arey haan tu last mein union keh rha, pehle 2 cases mein seperately toh intersection laga na x>3 AND x<4 so 3,4
x>2 AND x<3 so 2,3
uske baad union
Haa cases ke liye intersection
Saare cases ke regions ka union Lena hai
ok
got it
+solved @diamond @lmaodedXD @PINGUIN @ri?reeeeeeeeeeeeeeeeeee
