All of Graphs and Transformations in 30 Minutes! | Chapter 4 | A-Level Pure Maths Revision

Small correction at 3:56 the quartic equation should read as x(3-x)(x^2+4x+4) I must have typed a 2x by accident! Sorry 😬 👑 Everything you Need to Pass your AS Pure Maths Exam!

nice! Loving the hard work!

I was almost passing out thinking why my brain ain't working send the math to my teacher 😭

You deserve happiness and success!!

[@TheGCSEMathsTutor]

Thank you 😁🙏🏼

NO YOU DONT 🥷🏽🥷🏽 😭😭😭😭😈😈

[@evangelinasidawi]

at 5:36 how is the solution of the quadratic x+2? if you would add the them coefficient of x would have had to be 4 not 2

[@DEEZSHORT]

True, that caused a lot of confusion for me

[@Dazzletoad]

Wondering the same thing and now I'm left even more confused than when I started...

[@JddjeiurKaidickf]

It was a mistake don’t worry

[@maximum1866]

He explained it that the X coefficient should have been 4x instead of 2 but typed the time stamp wrong so there you go

[@straymite707]

what an excellent video thank you so much for making this i literally have a test on this topic tommorow. You're a life saver!

[@TheGCSEMathsTutor]

So glad to hear that! Best of luck with your test let me know how it goes 😁🙏🏼

[@ahmada7745]

hey think you made a mistake on 5:46 you said (x+2)(x+2) = x^2+2x+4 it doesn't it is = to x^2+4x+4

[@remz_tv5131]

Yh thought the same

[@silenct13]

I think he used this formula bro (a+b)^2 = a^2+2ab+b^2 so (x+2)^2 = x^2+4x+4

[@lizbasiita3498]

THANK YOU! I absolutely needed this for transformations.....my lecturer couldn't give me a method to memorize the principles...so THANK YOU VERY MUCH!🤩🤗

[@TheGCSEMathsTutor]

I’m so glad to hear I could help! 😁🙏🏼

[@GingerMathematician]

Good summary of all things transforming graphs 🙂

[@TheGCSEMathsTutor]

Thanks! Tried my best to summarise it in a very short period of time 😁🙏🏼

[@ItzAdz]

Thanks for this video!! It was very well done. It will help a lot

[@danzysgaming4311]

6:56, how do you know that this quartic is a positive or negative, like how do you determine tis shape?

[@ZOinu]

whether or not the coefficient of the x value with the highest power is negative or not

[@maysaali7632]

Thank you so much.

[@TheGCSEMathsTutor]

No problem at all 😁🙏🏼

[@zannino7889]

Great Video Watching this before my a level maths exam tomoz

[@abdurrahmanusman5854]

how was it

[@zannino7889]

@@abdurrahmanusman5854 ended up getting an A but was 1 mark of an A* 😭

[@kyllel]

could you do mechanics and statistics?thanks for the videos

[@Han_nahh]

Yes, please do that would be so helpful!!

[@ruxx9146]

4:35 how do we know its going to be a negative graph?

[@joe.b8358]

Because there is a negative X in the second bracket so when you times it all out you will have -x^4

[@Ghost-fh3lg]

19:26 hey , how do we use the a level calc to see the graph ? My teacher talks about being able to see on a calculator but I don’t know what he’s onab

[@LoONeY19]

I had a question in the graph transformations the one which got reflected (partb) it's y coordinate is supposed to be 1 right and not 0 . I'm not getting it

[@momina.k4024]

saved me in olevels and now in alevels too

[@RaidenTheTomb]

Hi at 3:45, why is only one point on the graph at x=3 if it's cubic n 3 solutions ?

[@Deadman2DX]

2 of the solutions are the exact same value - which is 3 in this case 👍

[@BarniDeDino]

I appreciate these my guy

[@Deadman2DX]

You can think of y=f(-x) as the x is being multiplied by -1 so it still follows the trend of doing opposites as you just divide by -1 to the actual x value for the transformation 👍

[@footballanalyst9283]

THANK YOU 🤩

[@imnotagirl2872]

Thank you soo much 💜

[@TheGCSEMathsTutor]

You’re welcome 😊

[@saharrahf2565]

at 04:36 why do we know it a negative graph

[@jesshenstock7645]

i don’t know how well i will explain this but

[@jesshenstock7645]

it has a positiv x at the start

[@jesshenstock7645]

and a postive x^2 in the second bracket

[@jesshenstock7645]

but in the first bracket the x is negative meaning that the x’s are negative so thta makes the graph negatuve

[@jesshenstock7645]

sorry if that wasn’t explained very well just let me know

[@m33sh50]

I was just wondering for the first two, do you not need to add in the points of minimum and maximum, when would you know when to add them in?

[@kashmiryy8820]

Cheers dude

[@TheGCSEMathsTutor]

No problem at all! 😁🙏🏼

[@TanatsaChigwida-iz4nq]

Great stuff

[@varunabishek5364]

At 24:54, the f(-x) is for reflection in y-axis. Similarly, it should have been -f(x) for x-axis. So yeah.

[@mangtypebeats562]

thats what he did?

[@simonwilkosz7562]

you legend

[@TheGCSEMathsTutor]

Thank you!

[@HaseebMuhamm06]

at time 30:06 watch out for the subscribe button it gets colourfull border around it when he says dont forget to subscribe the channel

[@Hermes108]

how delightful

[@riemashanaachandragantha4655]

does f(-x) not mean reflection in the x axis but in the last question it was a reflection in the y axis and i'm soo confused???

[@Hermes108]

thank you. these videos are very helpful. 👍

[@serden8298]

Great, fairly short video!!

[@nonsoottih7405]

5:58 your factorisation of the quadratic equation is wrong. The equation cannot be factorised cannot be factorised .

i was thinking more of a determinent tells us this and derivative tells us this sort of vid but its fine...mainly transformations
