hui uploaded 2 hours ago .. my iPod tells me that it is now 8:15 a.m. in San Fran so you uploaded it like 6 a.m. ... thats what I call dedication Sal!!!!! You rock :D
OMG thank you so much i have been searching for so long on this just trying to understand and I finally can!! THANK YOU SO MUCH …..I can finally bring my grade up!…
you just demonstrated a very basic form of model selection. I hope at some point, far off in the future, you'll introduce Bayesian statistics and their elegant use for the same purpose.
You reference "the next video." HOW do we FIND the "next" video?? Is there a chronology or numbering system we are missing? Son understands these principles but needs to write equations - wish we knew where to look :-(
Can someone help me with this 1) Find the vertex of the following quadratic. Then, plot 5 points near the vertex (including the vertex) and sketch the graph. 𝑓(𝑥)=−2(𝑥+4)2−3
((Linear graphs always look like a straight line with no curve. Quadratic graphs have a parabola shape. An exponential graph has a curve, but the curve will start out vertical 'n become more horizontal, or the curve will start out horizontal 'n grow to be more vertical (🏫👩🏿🏫👨🏫👨🔬👩🔬➕➖✖➗📔📚📝✏🍎❤🎒))).

why does my teacher have to not explain anything. I failed my test on this because I didn't understand it but when I come here I learn the stuff within 8 minutes like I hate my algebra teacher
Gamer/Tech Vidz It's not about linear Expo or Quad It's different from this video So if u know tell me okay So what kind of a function/equations multiplies the y value by itself to get the next y value For example: X=0,Y=2 X=1,Y=4 X=2, Y=16 X=3, Y=256 So is there a function like this or not? If yes what type?

45 seconds into the video and I've already learned something.
same, 45 secs and i got it
vs math teachers take 2 weeks and this guy does it in 45 secs lol

This literally saved me on my test thank you
Same here, lol!
I have my algebra end of course exam
And I'm here
I'm sooooo ded
same
EXTREME DInO Derp how did you do?
EXTREME Derp how did you do
How did it go

dedknd that’s an old comment
@@rebeccadillon1606 made me laugh! It is indeed, still have the iPod though ... somewhere.
@@reik2006 How old are you now, it's been 10 years like wow

oh my goodness this comment is so old
Amazing how calculus concepts where applied here .
Loved this video, great help, thanks!
Watching this 1 hour before my test, THANK YOU.
How did you do ?
Now I am convinced that algebra was created by Satan! Ever notice there's always 3 6's on the board somewhere everytime?😬😂
"If you only knew the magnificence of the 3, 6 and 9, then you would have a key to the universe.” -Nikola Tesla
U probably don't know the father of algebra, he isn't satan
I didn’t notice, that’s the Satan in your head 😮😂
I just want answers
Bro tbh this was so fun to watch and it was so interesting
Nice video Khan Academy!
Khan academy you've never let me down 🙏
OMG thank you so much i have been searching for so long on this just trying to understand and I finally can!!
THANK YOU SO MUCH
…..I can finally bring my grade up!…
Keep it up Sal, Keep it up!
It's a really amazing video I was really confused about it but you explained everything
yep """""change in the "ChanGE"
I was scared for a minute but I learned what I needed to
you're the man now dawg.
This helped me so much! Thanks!
you just demonstrated a very basic form of model selection. I hope at some point, far off in the future, you'll introduce Bayesian statistics and their elegant use for the same purpose.
thank you so much. you make me clear btw these models.
Thanks so much keep up the good work
Hi, is a mathematical function the same as a mathematical model?
Where did you get that blackboard software?
Very helpful.
You reference "the next video." HOW do we FIND the "next" video?? Is there a chronology or numbering system we are missing? Son understands these principles but needs to write equations - wish we knew where to look :-(
vivconable Visit his website KhanAcademy and it shows videos in order
it is fun.. thnx
Loved it, red heart, red heart, red heart.
this actually helped so much tyssm
what about other polynomials? (cubic, quartic...etc?)
Thanks
It was fun, thank you!
What if the table is not linear, exponential, or quadratic? It's just nothing?
yep
ur my boiiii
what playlist is this on?
Let me rephrase... What is he used to write with? It looks way too accurate to be a mouse but I'm not sure. Do you know?
im 10 years late but maybe a pen tablet (if those existed back then)
Learned this in 8 min then I did a week in class lol
Math is so annoying
Fr. Don't care that this was 3 years ago, it's still accurate.

Tinker Sbg do you still need it?😂😂
You still need it?
My good man, What software is this?
THANK YOU
he my homie
especially Algebra
In some of his older videos it's obvious that he used MS Paint, but it looks like he switched to something else - probably Gimp or Photoshop?
here before finals
Thank youuuuu
What about for cubic functions😢

No way
Noooo waaay
Probably a graphics tablet/pen.
I need help on my homework
math is not fun for me to do I'm sick of math really how do people understand it so easily??
So if the exponential function is on ^4 power, will change in change in change in change also be the same I wonder?
why does my teacher have to not explain anything. I failed my test on this because I didn't understand it but when I come here I learn the stuff within 8 minutes like I hate my algebra teacher
I have a math test on this wish me luck
@Gumrah Mammadli thanks! I can't remember what I got on the test but I did fine in the class
*I have ascended*
Hey can someone who is smart help me
I need help too lol
Gamer/Tech Vidz It's not about linear Expo or Quad
It's different from this video
So if u know tell me okay
So what kind of a function/equations multiplies the y value by itself to get the next y value
For example: X=0,Y=2
X=1,Y=4
X=2, Y=16
X=3, Y=256
So is there a function like this or not? If yes what type?
exponential function

Worst explanation to some but I kinda see it
