A-Level Maths: B8-03 Functions: Examples of Finding the Domain and Range

[louiepeters]

why are teachers on the internet so much better than ones in schools?

[mohamedasef]

thanks to TLMATHS, this is so easy and comfortable to understand with many separate details, pls continue to upload more content of a level

[aaryanramani]

You single-handedly saved my AS Maths grade. Amazing job Sir!!!

[aisyahfarah]

you are a lifesaver, i have my igcse addmaths tmr and i finally understand functions thanks to your videos

[ashh]

thank you so much that made so much sense and was so much better than what my maths teacher taught me irl, hes a really good teacher but on range and domain i got very confused and now i understand it thank you so much!

[brokke]

thank you so much! you make everything seem really easy

[olakitanemmanuel]

Nice knowing you sir. Could you pls make a video on how to find the domain and range of a modulus function. Thank you sir.

[tapiwanashegumbo]

I just want to say thank you so much may you be blessed with incompatible blessings

[tallula]

am I being too pedantic that for y=e^x as there is always an asymptote the x-axis, this means there will always be a value between the axis and the function which shouldn't be included in the range? or is it because this value will be so insignificant and small we do not need to include it? many thanks

[kevinjanuario]

great video but for the 6th example f(x)=lnx shouldn't the range be f(x) belongs to any real numbers but can't = 0 as it never touches the y axis

[mohsinnaqvi]

hey b0sS. you are great. any advise on as exams?

[celeb]

No 3 is incorrect to me cause I don't know why the line doesn't pass through 0

[enochp.]

For the 5th curve, f(x) = e to the power x, how did you determine where the graph crosses the y axis

[KA-xwth]

Pls is there a way to determine the range and domain of all these functions without necessarily sketching?

[sahilpahuja]

Hey sir just had a doubt,
Do they give these graphs already with the question or you have to figure them out and if yes then could you please let me know

[KA-xwth]

Thanks for the video. I really appreciate 🙏 💛 😌 ❤ 💓 💕 🙏

[Masowe.]

8:08 can i say f(x)>/=1 because the graph always cross at 1?

[Awai_quotes]

Hey sir i wanna ask at 3:55 instead of f(x)>0 can we write that f(x)belongs to natural numbers?

[lailafida]

Hello sir.can u plz find domain and range of modulous functions???

[clyven]

Thanks a lot, how to find domain and range using use of graph?
