Linear, Quadratic, and Exponential Models 

45 seconds into the video and I've already learned something.

This literally saved me on my test thank you

With khan academy, I mastered a whole school years worth of work in 14 days. Thank you so much. I'm very grateful resources like Khan academy exist. I made sure to donate to Khan academy today.

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

I have my algebra end of course exam And I'm here I'm sooooo ded

Amazing how calculus concepts where applied here .

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!…

Watching this 1 hour before my test, THANK YOU.

I just want answers

Bro tbh this was so fun to watch and it was so interesting

It's a really amazing video I was really confused about it but you explained everything

Khan academy you've never let me down 🙏

Loved this video, great help, 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.

yep """""change in the "ChanGE"

I was scared for a minute but I learned what I needed to

This helped me so much! Thanks!

Now I am convinced that algebra was created by Satan! Ever notice there's always 3 6's on the board somewhere everytime?😬😂

Nice video Khan Academy!

Hi, is a mathematical function the same as a mathematical model?

you're the man now dawg.

Keep it up Sal, Keep it up!

what about other polynomials? (cubic, quartic...etc?)

Very helpful.

thank you so much. you make me clear btw these models.

Thanks so much keep up the good work

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 :-(

this actually helped so much tyssm

What if the table is not linear, exponential, or quadratic? It's just nothing?

Where did you get that blackboard software?

Loved it, red heart, red heart, red heart.

it is fun.. thnx

My good man, What software is this?

what playlist is this on?

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?

It was fun, thank you!

Probably a graphics tablet/pen.

Math is so annoying

ur my boiiii

Thanks

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?

Learned this in 8 min then I did a week in class lol

What about for cubic functions😢

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

I need help on my homework

especially Algebra

he my homie

here before finals

So if the exponential function is on ^4 power, will change in change in change in change also be the same I wonder?

THANK YOU

Thank youuuuu

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

No way Noooo waaay

*I have ascended*

math is not fun for me to do I'm sick of math really how do people understand it so easily??

Hey can someone who is smart help me

((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 (🏫👩🏿‍🏫👨‍🏫👨‍🔬👩‍🔬➕➖✖➗📔📚📝✏🍎❤🎒))).

Worst explanation to some but I kinda see it
