How would you do a tree diagram for that sort of picture?
I'll draw one in a second for you

y= f(x) is that likely to come up and could you explain it

y= f(x) is that likely to come up and could you explain it
y= f(x+a) shifts the graph to the left depending on the value of 'a'. For example, say the minimum point of a curve is (2,4) and it asks you to sketch y=f(x+2). You would shift the curve 2 to the left, so the minimum point would be (0,4).

y= f(x-a) shifts the graph to the right. Using the above example, the graph would be shifted to the right by 2 units, so the minimum point would be (4, 4)

y = f(ax) stretches the graph by a factor of 1/a parallel to the x-axis. Say a = 2 and the minimum point of the graph is (2, 4). The graph would be stretched by a factor of 1/2 parallel to the x-axis, so the new minimum point would be (1, 4).

y=f(-x) reflects the graph in the y-axis. If the minimum point is (2, 4), the graph of f(-x) would have a minimum point of (-2, 4).

y= f(x)+a moves the graph upwards by 'a' units. Again, say if 'a' is 2 and the minimum point is (2,4), the new minimum point would be (2, 6).

y=f(x)-a moves the graph down by 'a' units.

y=-f(x) reflects the graph in the x-axis. If the minimum point is (2, 4), the graph of -f(x) would have a minimum point of (2, -4).

y=af(x) stretches the graph by a factor of 'a' parallel to the y axis. Say a = 2 and the minimum point of the graph is (2, 4). The graph would be stretched parallel to the y axis by a factor of 2, so the new minimum point would be (2, 8).

So basically, if 'a' or the minus sign is inside the bracket, it affects the x coordinate of the point but if it's outside the bracket, it affects the y coordinate of the point

Hi there I have not been revising this new spec of functional math, so can you please do me a huge favour and give me the topics that are most likely to come up in the C paper and NC paper. Can you also tell me on what you think of this new paper because I've been hearing that this is exam is going to be extremly hard than the old spec.

Hello, well it is almost impossible to predict what is 'most likely' to come up, and trust me when I say that (hours of revising probability ) however if you take a look at the papers I have attached throughout the thread you will find papers from the new spec. From that you can decipher the format and get comfortable to the setting and well to be honest the exams all hyped up about how hard it's going to be..
There's two possibilities:

A) The exam will be really easy, all the hype around it was only because it was a new specification and there has not been any actual past papers & therefore the grade boundaries will be near the standard 165/200 for an A*
B) The exam will be really hard, the material Edexcel has given out is to prepare us for a hard exam, therefore the grade boundaries will be nothing more than 140/200 for an A* grade.

Regardless of all this guessing: Just revise hard and you will do great!

Thanks and can anyone tell me any ways that could help me revise effectively as I haven't started yet and how many hours I should do.

Thanks

y=f(-x) reflects the graph in the y-axis. If the minimum point is (2, 4), the graph of f(-x) would have a minimum point of (-2, 4).

y= f(x)+a moves the graph upwards by 'a' units. Again, say if 'a' is 2 and the minimum point is (2,4), the new minimum point would be (2, 6).

cheers that makes lots of sense

Try doing as many practice papers as you can. You can find them on the Edexcel website - or some of the guys have posted some on the pages before. Do one paper, have a break then mark it, go through your mistakes, find your strengths and weaknesses. Then try some practice question for the topics your weak on from your text book. Afterwards do more paperssssssssssssssssssssss!!!!! !!!! :I know it sounds long but I guarantee it helps
Good luck guys!

Thanks but do you think doing pat papers is a lot better than doing work from the revision guide because to be honest I haven't even looked at it once :/

LOL i haven't even touched my revision guides and i have 5 different ones! The past papers are helping me a lot because unlike other exams you can't predict what's coming up - if you get me? Like say in physics newtons law came up last year and your teachers say it wont come up this year because it already came up. Thats the thing in maths the same topics come up year after year - every year there's algebra and stuff. So by acing all the past papers you can be sure the same questions come up but with different number.
I chat **** :/

Thank you so much I'm going to start doing that

hey, guys does anyone now if the exam is am or pm iam soo screwed for this exam
15. Haha I took edexcel maths in march when it was the old spec! I'm so happy i got it out of the way! Good luck guys I am almost sure that it's going to be a really difficult test so the grade boundaries will be really low!

Does anyone know what the grade boundaries for the 1MA0/3h Set A Non Calculator may be? Would 80/100 be an A* or an A?
Thanks

I'd say it's an A* but there are no set grade boundaries

It's alright

When it says estimate (34.5 x 21.2)/0.46
What do you do?
I know it's basic stuff,but I will probably slip up on some basic things.

Round the numbers to nice, easy numbers and then multiply/divide them

In this case, I'd round 34.5 to 30 and 21.2 to 20. And I'd round 0.46 to 0.5
