Effect of a,b,c on Quadratic

The graphical affect of parameters a,b,c of y=ax^2+bx+c on the graph of a quadratic

[@VinayK22]

best video ever on parabola, and no one teach this... this is most basic thing one should know

[@asquareacharya8837]

About "b" is tricky...wow Thank you

[@shreyah9938]

This helped me so much... I was soo confused but your video really helped!

[@selvanaiyadurai8967]

Excellent work Mr.David!. Great service to students.

[@endfel3561]

Finally I understand what each value means, underrated video

[@danmeiweeb97]

Thank you so much... You made it so easy to understand... Was getting confused again and again... Thanks a ton!!

[@mankisser1337]

thanks to you i can get my math final done :)))

[@spunkymonkey5102]

why the hell don't they tell us this when it's so simple. I was under the impression the bx was just too advanced for us to understand yet so all we needed to know is that it was part of the quadratic formula, but all it was just the slope at the y-intercept.. The only justification I can think for this is that they may want to teach derivatives or something first but it's not that complex to need knowledge of instantaneous slope. I have suffered since 8th grade, agonizing over what cryptic meaning it must have what a let down

[@battlecoucher]

Oh man, the effect of the B value hit me in 4:34, fire video to this day

[@devarshbimal4186]

Absoulte legend for explaining this ❤❤

[@cloudy_fire_1527]

you explained that like a champ

[@AlessandroZir]

thank you so much!! it's very intuitive to see this; I've been searching for a video like that since a long time;

[@JussyWussy]

Great video, a classic. I've found that all simplistic and well-explaining math videos are at least 10 years old!

[@TheUniverseBrewer]

Thank you for actually explaining this instead of saying ‘b is the coefficient of x’ 😂

[@aladinabrash7465]

Perfect explanation

[@eddied1695]

Really helpful. Thank you.

[@CoolDude-xe9ir]

Turn on the captions to understand the concept (its a very good explanation) thanku sir

[@seanmaclean706]

Fantastic video. Thank you!

[@firstkaransingh]

Thanks so much.... This was very helpful. Finally understood why quadratic equation forms parabola.

[@potatosacksss518]

you are doing god's work

[@devanshutalreja8458]

Ty u sir this helped me a lot

[@khushipriya2548]

Thanx a lottt..

Thank you!

[@rudradhamecha]

thanks bro

[@leucopsarrothschildi]

wow thanks a lot

[@robinofautumn99]

thnx a lot sir

[@sanaarshad4681]

Thank you.

[@anshpatidar5842]

Thank you sir..

[@anshulkaushal1177]

Thanks

[@ml106]

Thank you for the video. It was very helpful and it served its purpose. Just, may i ask which like program you use to present these different functions ? It would make things easier for me to better understand as i continue studying.

[@dlippmanmath]

+Muky Tack That particular program was a custom thing I had thrown together. If I was doing the video today, I'd use the desmos.com calculator, which can do sliders the same way.

[@ml106]

+David Lippman Thank you again for the quick reply. I will definitely check that calculator out. I wish you success in your work. :)

[@sharonnn82]

hi i just have a question! so why isn't there a parameter that just shifts the quadratic left and right simply, like c?

[@tebogo743]

This is how he should have explained it Say for example we have(the question is draw a rough sketch of a parabola/quadratic function) a>0 which means it's a positive number b>0 which means it's a positive number c

[@johnadderson5148]

B is slope of the tangent line of the parabola at point (0,C).

[@_asrar007]

What's the name of this software, where you play with graphs?

[@mahvishaman]

desmos

[@tiathathiah9861]

Brilliant thank you

[@burlofreak]

cool it bro ur blowin out my speakers

[@Omniscient01]

I've been playing with a parabola for 30 minutes now. Reality can be whatever I want.

[@ckzombie1130]

Which program or software did you used for graphing in this video? Thank you.

[@arieloguche416]

Desmos graphing calculator

[@siddxstar]

500th like...😁

[@keezothefool]

Still don't get it.

[@tebogo743]

[@ekaterinafeldman5394]

May I please ask what program you are using? Thank you

[@JussyWussy]

Desmos can fulfil the same purpose and function mate

[@sami-sk1bu]

THANKS

[@CleetusTheFish]

I understood not one word im doomed

[@tilak09]

Wow ❤️

[@mossycryptid]

does anyone know what graphing tool this is?

[@arieloguche416]

Desmond graphing calculator

[@vaishaligoel2321]

Could your voice be any softer

[@vaishaligoel2321]

Ain't nobody asked for your worthless opinions. Not my fault this dude has horrible audio settings. Could you be any dumber?

[@angelq9863]

Vaishali Goel Noone asked for yours either, why do you have to be such a bitch? The dude in the video is just trying to help.
