T Domain and Range of the Function Part -2 , Class 11 Mathematics

[@mathwizard7264]

In range there is a calculation mistake there denominator will be (y -3) => y can't be equal to 3, so Range will be R={y : y ∈ R ,y≠3}

Ma'am plz continue.. excellent lecture ❤❤

[@ArunKhokhariya-sj3or]

Keep it up nice explanation 🎉🎉

[@AayushbistAayush]

And number one as you say set of real number- 3 - 1 I got it but why not -2 included

[@mathwizard7264]

All real numbers (including -2)

[@mathwizard7264]

I just took -3,-1 to make U understand.All real numbers _____. -3,-2,-1,0,1___

[@AayushbistAayush]

And you said in question number 4 that (is mean to 3 is not included but I think] means three is not included iam confused 🙄🙄

[@mathwizard7264]

@AayushbistAayush Ayush I couldn't get your question . In domain I said 3 is not included but in rage there is a calculation mistake there denominator will be (y -3) so Range will be R={y : y ∈ R ,y≠3}

[@Sameh-Samir-Isk]

range in 4 is wrong it should be y=R-{3}

Agreed
