Hi Ray, Congrats for this Clear, Concise and Objective explanation about Vertex Form of Quadratic Functions. I would be able to give you, at least, 1,000,000 Likes.
the coefficient in front of the x^2 term, called "a", alone dictates whether the parabola opens upward or downward. "a" was unspecified at 4:23 but can be assumed to be negative in that example.
That two that you split from the standard form, is that done to all problems, for example if there was just a variable would you take the same variable and apply it to the split inside term?
Dear Ray can you please upload a similar video regarding paraboloid. I ll be gratful to you if you also include cylindrical coordinate for drawing paraboloid
This is the most complete, indepth explanation I've seen on the subject matter. Well done!
so true

Your video really helped me understand standard form and vertex form easily and clearly. Thanks a Lot!
Wow this has been very helpful ! I hope to see more videos like this one
Thanks for the video. There is clarity in your presentation.
this is just ... a perfect explanation
why not million likes for this video? it is simply perfect
Best video on the subject I've ever seen. Wish we had videos when I was in high school.

I appreciate your video, thanks Mr.Dempsey
We need a petition to bring him back !!
very helpful and clear, keep em coming!!
You are the best and the best explanation ever.
Beautiful explanation and nice animation. Thank you
Thanks so much Bro Demsey you really saved my ass from failing.....
Hey Ray, I must say this was a very concise and thorough presentation... aka gangster...
Excellent
very impressive explanation
Its really short and sweet... superb.
Great video !!

Amazing! Keep going with the videos!
excellent
that's amazing!! well explained
Best explanation ever
Thank you very much this video help me a lot
good explanation...
GREAT
at 4:23 why is the parabola opening downwards..since the coefficient of x is positive shouldn't it be opening upwards..?
+Kshitij Mishra yes. when a is positive its a minimum and when its negative its a max ( in terms of where the vertical placement of the parabola)
+spiddyman007 Then why is it opening downwards sir?
+Insanes Productions i don't know. Ask ray dempsey
+spiddyman007 Sorry I was thinking it's your video

so amazing
nice

thank for the video
Can the parabola be tilted wrt y axis. How can it be done
perfect
Thanks man, No summer school for me
nice
What difference between angle and parabola can we write equations of angle
Please answer 24/4/2020
🙏🙏👍😊
W-WO--WOW
perfect
