Excellent Video. Taking Pre Calculous through virtual school this year and I was asked on an assignment about mapping rules, but in all my years of math (being in an actual in person class) I’ve never heard of mapping rules before.
I'm just trying to understand it better as my teacher uses the Waterloo standard with the general equation presented in the form of y=af (b(x-h)) + k . This is the form he will use on tests. But homework sheets will refer to the equation in the general form of y = af (k(x-d)) + c. I'm currently trying write up my own notes to see if I can understand how to do mapping enough to figure out my own homework questions
Hi Ms Harvot! I just want to thank you immensely for these videos that have helped me progress through the grade 11 functions course. Can you please do an video on solving linear inequalities? And by any chance post an practice worksheet on your website?
There is no section on solving linear inequalities in the grade 11 Nelson textbook. I am just looking for examples and extra practice. May I know which video you posted on linear inequalities? I apologize for bothering you.
Thank you for all the help. I just have one question, is there any questions in the Nelson textbook that you would suggest doing just to study for a chapter 1 test?
When you have a quadratic function (when the degree is 2, as you know) the easiest way to describe the transformations of the parent function y = x^2 is to put the function in vertex form. However, with other functions vertex form is not a possibility so we use mapping rules. It will become more clear as you work your way through the various parent functions such as y = 1/x, y = a^x, y = sinx etc.
You will. Have confidence in what you have learned! Being prepared brings success. This is definitely the hardest chapter. Everything else in the book stems from these lessons. Thanks for watching and let me know how your test goes!
Hi, Ms. Havrot, I am doing advanced functions and this whole chapter of Math really helped with transformations and understanding how they work for polynomial functions. However I was confused about one thing and if you could provide some insight on this that would be awesome. So basically in polynomial functions to grasp the equation from a graph you can just solve for a by solving for the input values and then dividing by the output to get the a value. In this section is this not possible? And if not then how would you go about solving for a? or even k? as always thank you for this resource you have provided for us students.
I’m not sure what you would like to know. Can you point me to a textbook question that I can explain for you? Also, I never taught input output as I thought it confusing.
Ms. Havrot, on question 15 in the chapter review, i applied (x/k+d,ay+c) to the point (1,4), and i got (-5/4,10), but my nelson textbook says its (-5,10). The only way to get that is x times k. Did I do something wrong? Or is it the textbook? Thank you.
Hello! Your videos have been really helpful while pre-prepping for Grade 11. I have a question about this lesson. In the new equation we learned, for the x transformations k and d, why do we multiply the x value by k first? If its in the bracket, shouldn’t we add d first? Any help would be greatly appreciated
I’m not quite sure what the equation you are working with but the k value should always be factored out of the bracket in order to get the proper horizontal shift value. You always multiply by k first … remember that in order of operations multiplications are always done before addition and subtraction.
If you do not factor the 1/3 out then you would have the wrong horizontal shift. You would have said horizontal shift left 4 instead of a horizontal shift left 12 units, which is the correct answer. Tell me where in the textbook you saw this please.
This video is super underrated!! Clear and concise video, thank you so much!!
Why thanks Ayesha. I used to teach an Ayesha ... she was a lovely girl, just like you! ❤️
What a teaching ma'am, you are the best math teacher I have ever seen in my life so far. Thank you so much for the videos.
Wow, thank you! 😊 Thanks for watching ❤️

This really helped me for my test tomorrow! Never got it in school but I finally get it today. Thank you!
Glad it helped!
Outstanding examples and explanations. Thank you.

Using h and k generally refers to quadratics where (h,k) is the vertex

I know I have done a video on inequalities. Can you tell me what section in the book that you studied them?

Fantastic lesson
Thanks! Glad you enjoyed it! ❤️
How do you know when to use the transformation of functions formula vs vertex formula, it’s confusing for me
When you have a quadratic function (when the degree is 2, as you know) the easiest way to describe the transformations of the parent function y = x^2 is to put the function in vertex form. However, with other functions vertex form is not a possibility so we use mapping rules.

thank you so much from Singapore
Wow! So nice to have subscribers around the world! 😊. Thanks for watching!
This video was very helpful! i was wondering though, what is the purpose of the f being there? do we just ignore it?
I believe you are asking about f(x)? If so read it as the function at x. It is now replacing y.
this goes hard 💯💯💯 thanks yo heres hoping i do well on my test tomorrow ;p

ay i have a transformations test in two days too

I agree with your answer. It’s 1 /(-4) - 1 so you are correct.

The textbook says you don't need to factor the 1/3 out in question 16

it says in the answers in the back sorry I noticed they didn’t respond
The textbook has lots of mistakes

Plz how do you solve this. Finding the rule of mapping
x 1 2 3 4 5

y 10 9 8 7 p
I’m not sure what this question is, but I would say p = 6 based on the pattern.
