For Min Turning points:
Say you have the equation , that can be written as: .
To find the minimum turning point, you need find the point where y is at its lowest value. So therefore, you want the point where is at its lowest value. You can't do anything about the "-3" bit, that's a constant, but what you can do is to make as low as possible. You do that by making x = -2, so that you get , if x is any less, or any more, then you'll get a positive number for that part of the equation. The key is to make the value inside the brackets be 0.

So now you know x is -2, what is y? Well, you just plug in the values so you get , this is just the value outside the brackets. So the minimum turning point for is . See if you can do the same for the maximum turning point of
Thank you so much!
If you had a negative x coefficient, would you have to change all the negative signs to positive signs? I'd work it would with a pen and paper, but I don't have any on me at the moment.

Hi,

Nice to meet you! I just starting rereading Jekyll and Hyde. I also read it at the start of year 10, somehow my teacher felt we'd remember everything.

I understand the maths struggle. Tomorrow, I have a maths test on everything we've learnt. Do you have a mathswatch login? It saved my life last year. Bitesize can be useful also and I recommend getting a revision guide - I have the CGP 9-1 revision guide.

Hope this helps
I've never heard of mathswatch before. I'll go check it out now! My old maths teacher (who was great; I was able to move up a set at the end of last year) said Corbett Maths was really good. I got some practise papers and the like from there, and loads of other people in my class said it was great.
How did your maths test go?

You complete the square normally and you'll see there will be a negative sign in front of the brackets. You have the make the whole equation be as high as possible (that's why it's called max turning point) You still do the same thing though (make whats inside the brackets 0).

Corbett Maths? I'll check it out, thanks for the advice.

My maths test was pretty terrible. It was nothing like the past papers! Or even specimen papers! Nothing could have prepared me for that. I doubt I even got 50% correct and we have our third paper on Wednesday.

How about you? Any maths tests?

Maths tests always go terribly. The thing you've got to remember is that it went terribly for everyone else as well!
No maths tests yet, but I've had one in chemistry, one in physics. I have a biology one on Tuesday and a Spanish one next Wednesday. My French teacher has warned us that's we'll be getting a controlled assessment task within the next week or so. We're finishing our geography course work, so we have a high-control assessment coming up soon.
Such fun.

Surely that would mean x would have to be infinite, then? Can you get x as being infinite?
7. Hey
Has anyone done the aqa pixl paper for english lit?

because there's a minus in front of the , making x infinity will make y be negative infinity. You want the bit inside the brackets to be as close to 0 as possible, since you're going to end up squaring it, but then also making it negative.

So x would be +2?

Yeah, the maximum turning point is

12. Hello, i'm aaron1050
I'm an avid gamer, maybe too much lol, and i'm interested in chemistry.

At GCSE, I'm doing:
Maths - OCR
English Language - AQA
English Literature - AQA
Biology - AQA
Chemistry - AQA
Physics - AQA
German - AQA
History - OCR
ICT - Edexcel/Pearson
RE short course - OCR

I think i'll be ready for the new maths spec, but i'm worrying about English!
Favourite subjects are Chemistry and history.

For A Levels, I'm thinking maybe some of: Chemistry, History, Psychology, Sociology, Maths, Physics but i'm still not sure.

University I would like to study a branch of Chemistry, possibly Organic.

Dream career is to become a chemist in industry or to become a teacher at secondary school-level.
13. I lovvee gaming!! I like to play Cod and Transformice ( which is gonna have to stop during this year ) I guess I'm kinda ready, my dad is already getting me a maths tutor so I can boost my predicted C into at least a B

My subjects are:
Maths *Edexcel*
English Lit *AQA*
English Lang *AQA*
Religious Studies *Edexcel*
Food Technology *AQA*
Geography *Edexcel b*
Art *AQA*
Biology, Chemistry, Physics and ISA (coursework 25%) *AQA*

I feel as if I'm gonna do pretty well, I'm doing homework and I'm starting to revise- however I feel as if by the time it hits May 2017 I'm gonna forget all my revision due to Anxiety and pressure . I pray that doesn't happen

We have had a topic mock, but no full-on mocks yet. They are in January I believe.
17. Hey
Is anyone doing ocr b triple science?
If yes have you done the osmosis bio controlled assessment??
