we had this during grade 8 but I totally forgot all about it and because school just started we are reviewing past lessons. my teacher makes it really confusing and his grammar makes it a whole lot worse! thank you!! you're a life saver

I cannot thank you enough for these videos. They are extremely helpful to me. I need all the help I can get :D

Thank U very much sir....I was very much confused with the Concept of Range.....but Now its clear as U explained it Graphically....Thank u very much once more sir.....Excellent !!!!

My A level exam for Pure Mathematics 1 starts in less than 5 hours so this helped

Soo much better than my teacher in school, she never explains anything properly, unlike you.

Thank you so much since I just started in the K to 12 curriculum, I have prelims to answer this for I'm not a good mathematician but a great listener. Thx

Thanks for this vid, finally someone that can explain it to me clearly enough to stick to my mind.

I’m in my 3rd year of Uni taking mathematics of natural science and it’s hard because my prof assumes I remember everything from trig and algebra and all but it’s been over 3 years since I’ve taken a class like that so I feel so incredibly behind. I’ve always liked math but I’m struggling a lot rn

It's so easy to understand ! life is like trying to set up domain and give it's a law to get a range ,thus we can get a different life .

crying cuz i forgot all about this and have to relearn it all 💀🤡

Thanx a-lot u are helping me .. thank God 🙏for having good ppl who would love ❤️ to help others for nothing .

Thanks so much from 12 years after the release of this video.

Best explanation! Finally understood!!

this is very helpful, thankyou!

thanks for this. this is awesome. I'm starting to enjoy mathematics

OMG This is actually so good

Thank you, you make it look so easy.

"JAI HIND DOSTON "🇮🇳

Hi Sal, pretty well with the graph explanation but make it a bit simpler. Find f(x)=y such that the determinant is negative and the number turns imaginary. Since for y=-5, you get 3(x-1)^2 and hence the determinant must be 0 because there are equal roots, any y below -5 would make the discriminant 0 and hence the range is [-5,∞). This is what I was taught in 8th grade.

Thanks alot its really helpful

Awesome. Thank you . I had this question on the assignment due after march break . Thank you .

I spaced out most of my class so Kahn Academy don’t let me down :,) I’ll update and see if this helped me Edit: IT DID I MAKE A PRETTY GOOD GRADE ON MY TEST

One can also calculate the range by using differentiation... That'll make it easier. But yeah, this falls into algebra, before the calculus. So, great. Btw, thanks a mountain for this video! 🎉
