This video shows how to use vertex form [i.e. y = a(x - h)² + k] to graph a parabola or use it to write an equation from a graph. This lesson was created for the grade 10 academic math course (MPM2D) in the province of Ontario, Canada.
I can't thank you enough, my teacher isn't really a great explainer and when you do this I understand how everything works. If you never did this, a lot of people would fail math. THANKS :D
Even thought this was only part of the lesson for me thats going to be on the test,youre still more helpful than my current math teacher ever will be. Hes not enthuisiastic about teaching,always leaves the lights closed, mumbles, and doesnt offer tutoring after school or at lunch,and most of all no one understands his teaching. In short, you da real mvp.
I already understood this but now that it's exam season I couldn't remember how to graph y=a(x-h)^2+k when the value of a is a whole number or a decimal. This was super helpful and way easier than how my teacher taught this. I could tell this was a teaching from Ontario because the font from this page looks exactly like the one in my academic math book. The wording is also very similar. Thanks for the help!
This basically saved my life. Thank you so much, I've never had a teacher teach this material before (let alone mention it) but I needed to know what is was, and how to apply it because it has to do with my senior final math project. Seriously, I cannot thank you enough. Now I can complete my product, and finally get some sleep.
Oh God, I was looking for an explanation of this but I couldn't find anything in Spanish, since it is my language and I take maths in Spanish, but anyways, I think you really helped me. Thank you so much.
Uriah DelGrande I had to find the axis of symmetry and the vertex from the parabolic function y = -x^2 - 4x + 8 what do i do about the negative x^2? I was told to multiply both sides of the equation by -1 as the first step, but then the y was negative; I dunno what to do lol, I have an exam tomorrow
I sent you a message directly on your channel page. Not sure if you got it. I am also a teacher in Ontario. I assume you are using Powerpoint for your videos. What do you use to capture and create your videos? How do you include graphs in your presentations? It seems that you are able to draw the graphs within Powerpoint.
Michael Cammock Hi, Sorry, I just saw your comment. Yes, I use PowerPoint. I screen capture using Camtasia Studio 7. Its made by Techsmith. I draw all my graphs within PowerPoint using its draw features.
Great. Thanks for the response. I need to investigate the draw features in Powerpoint. Not sure how that works in relation to graphs but I am sure someone has posted instructions somewhere online.
AlRichards314 Okay, thank you. My math class is online and they teach you everything in text instead of showing videos or math problems being solved so learning the more unusual formulas is really difficult and I need to use outside sources. Videos like this are really the biggest thing helping me get through the work since the way I learn best is seeing a problem solved and then repeating it. I can't have something explained verbally so reading math problems is next to impossible for me. Thanks a lot for taking the time to do videos like this!
Keith Richards No, normal factoring gives 2 sets of brackets, but with completing the square both binomials will be the same, that's why there's only one bracket and it's squared.
y = (x - 2)² + 1 is the same as y = 1(x - 2)² + 1, so a = 1. It's the same idea as x is the same as 1x. There's an assumed 1 there, when you don't see a number.
Sorry, I can't help you with that, but I'm glad you found my video useful. Check out the video organization link (yourmathvideos) if you are looking for something in particular. It's organized by course in our province, but you can fairly easily find a specific topic.
