Great vid. The thing is tho... they bring in questions that really require wider knowledge outside spec, i mean... to find that range of g, you really need to know how to sketch that function, but its not officially taught in the textbook or is part of the spec.
You're spot on, sketching these rational functions are really important to find the range. We also feel that this should be made clearer in the specification.
@@pigeonlove Yeh, but it doesnt end here... list goes on and on in the new spec... eg. They like to give quadratic modelling questions where you have to find a quadratic... this can recquire more specialist knowledge that is not covered the way it should be in the section of Quadratic modelling of the Year 1 book. Its Pearsons idea of a "Synoptic" paper...
For question range at 18:00 I prefer to put infinity (x can get this large in domain) in the denominator to get zero - as the denominator gets super huge to tend towards zero.
Hi Sir, the video was great for practice so thank you . At 4:22 , would this method of finding the assymptote work for every reciprocal graph? Or does it depend on some conditions being met ?
This might seem like a slightly obtuse question but how do you make your videos with the exam paper and writing as you go along and recording the sound all simultaneously. Is there a particular program you use? Thanks and apologies if the question seems really dumb
No g(x)is a many-to-one function. The first term 'many' we use to describe the y values, the second term 'one' we use to describe the x values th-cam.com/video/esAf4gWDJNY/w-d-xo.html

If that is true, it should be reported to the board. There is supposed to be a team of people competent enough to set the appropriate questions.

Great video, would you please create a series of these a level topics before the exam Greatly appreciated.😊
with time we'll have everything. We're looking to grow the team so we can have more resources for you.

havent even watched the video yet but thank you for this

cheers
For question one b, if x is greater than or equal to 5 shouldn't the range also be greater than or equal to 5?
44:50 why does the denominator = 0? Shouldn't anything that makes the denominator = 0 be undefined? And undefined doesn't equal 0

Hello sir, may i ask for the pdf of the materials in this vid??? 😅😅 Greatly appreciated if sir is willing to provide the materials 😊😊
Sure send us an email at info@examsolutions.net

@@nkyxd5698 can you please send it to me if you have it. Thank you
at 28:00 isnt it supposed to be one to many for g(x)?
i thought many to one could have inverses
bro im confused h(x) is also a many to one since its a quadratic
No g(x)is a many-to-one function. The first term 'many' we use to describe the y values, the second term 'one' we use to describe the x values
