Draw Cubic Graph Grade 12

[@wyattcleaver1942]

Thanks Kevin. I've been watching your videos since grade 9 and you've gotten me through to grade 12. I write my prelims in a week and I'd like to say you're amazing sir. Thank you for what you do 🙏🙏

A cheat I have is I add the equation to the table setting on our calculator then work backwards. I get all my points from seeing where F(x) is 0 on the table

[@blessingdiza7573]

It works thank you😭😭😭😭

[@H.o.o.d.R.i.c.h]

It works perfectly

[@owethuhadebe199]

thank it helps🤗

[@Sephorakankonde]

You have to explain this to me 😭

Bro😭😭😭

Thanks!

[@kevinmathscience]

Thank you so much!!

[@sibongakonkenqayi9493]

sir i think it gonna be way easier if you teach them the synthetic method:)

[@dillannaidoo5543]

yesss

[@itumelengmapitse5835]

I agree,my teacher did it and it was way easier to remember but since i didn't write the method down I forgot how to do it but my past questions helped me understand again and I fully recommend it

[@flo_riieyxoxo8905]

Writing p1 tomorrow ...class of 23 🎉

[@The_dark_stallion01]

Same situation in 2024 so ironic 😂

[@rye1903]

there is an easier way to get all your x-ints. Use Mode/Setup then choose 5 then choose 4 and plug in values. Get your answers for the x-ints and then work backwards to get all the calculations that they want to mark. Easy hack and no one has to know you used a calculator. Saves time in exam. If you wanna get a better explanation just ask and i will explain properly.

[@Sephorakankonde]

Please explain further🙏🏾

[@twobirdsssss]

Can you pls explain further

[@Justin-uw9yw]

10 months later and you still haven’t explained!🙄

[@dhejsj-y3g]

Omw this actually worksss But you still need marks for working it out, still good tho thankss

[@leagomodisane4818]

Hi @Kevinmathscience. My math teacher taught me a way to find the threw x-int. without guessing. You simply try all of the factors of the last number, in this case 8, and one of them will be correct

[@lizzolisa9068]

Yah nehhh😭😭😭I'll just use long division

[@nikiwe1307]

Didn't they say we are not allowed to use that one😭

[@NeoGotMyBackTheSkothane]

Use the synthetic method!!!!

[@kirstensmith5051]

Hi Sir I can’t find the next videos where u show us how to find the y-int, T.P. , inflection point and how to plot the graph

[@kevinmathscience]

Hi Kirsten, i see that i have not added this on KZbin yet. I have made a note to do it within the next day or two. My online course has ALL the videos. If you are Interested please check the video description.

[@Dr_Klittorhys]

Thanks Kevin🙏 I always come to you for revisions(tomoroow im writing my final Promaths paper 1), you so good i just wish you did Life Science and Accounting.

[@kevinmathscience]

Wishing you the best with the paper :) Sorry about the accounting and Life Sciences.

[@dylanlaithwaite2694]

Check out a channel called Mindset, they have some biology stuff that are pretty good :)

[@stonespammer7125]

This is now in the year 10 methods syllabus in my school

[@abdulmunimcolbie1814]

Won't your inflection point always be the middle value of the x intercept? So must you still show your working when finding the inflection point?

[@duckalotl]

Might be a but late but yeah it is the middle point of the turning points so you dint need to show ur working

[@abdulmunimcolbie1814]

@@duckalotl thanks bro😭

[@saucey767]

kevin can i do the long division method???

[@areereethly6660]

great video, thanku

[@saucey767]

i do the long division method is it reliable?

[@yasinahmed8019]

Is der an easier method?

[@kevinmathscience]

Not really although there are different ways to find x intercepts. So you can use different methods there. Either follow your textbook, your teachers method or my method :) Here are some videos for x intercepts: kzbin.info/www/bejne/ip_cZ4x4hbh9gaM kzbin.info/www/bejne/qmisgYysadyqlc0 kzbin.info/www/bejne/m5qxeJ98jpdlpsk

[@realdestinyentertainment6813]

Kervin please assist. I tried to test -6 and it give me B=2 not - 2

[@evolve4609]

same

[@lllll8449]

Hello there is also a possible answer of -2 for this sum what do you then ?

[@kevinmathscience]

So then your first bracket will be (x + 2) (Ax^2 + Bx + C) and then you follow same technique that I used in video :) You will get same answers at end! :)

[@itssamiey299]

am i trippin or x squared times x is x cubed?

[@IAMBATMAN...]

Ofc, just add exponents

[@vunolwethu]

sir which syllabus does this apply to

[@infiniteso3430]

Calculus

[@kevinmathscience]

CAPS/ IEB

[@dimphomahlanya1512]

How do you find a,b,c if you are given two turning point

[@kevinmathscience]

A turning point is where f'(x) = 0 So take the starting equation they give you with all the a's, the b's and c's and then take first derivative. Make it = 0 and then plug in the x value they gave for the turning point. Then do it again with the other turning point. Eventually it will end up becoming a simultaneous :)

[@lizzolisa9068]

​@@kevinmathscience yohhh 😭😭why isn't calculus taught in the first term😭💔it has alot of content and we writing in 2 weeks and we aren't done with it yet

[@Spyce_mthola]

​@@lizzolisa9068 bro imagine 😢

[@meezy7864]

Hi kevin uhm I substituted-2 in whereas you substituted 1 and i got 0 aswell? Im confused

[@kevinmathscience]

Yes this can happen :) When this happens you can choose any of them and you will get all 3 of the same at the end :)
