Linear, Quadratic, and Exponential Models

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

same, 45 secs and i got it

[@mathmanchris666]

vs math teachers take 2 weeks and this guy does it in 45 secs lol

[@sarahhickey204]

This literally saved me on my test thank you

[@JChillz_]

Same here, lol!

[@mathmanchris666]

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.

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

Loved this video, great help, thanks!

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

[@alkalait]

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.

[@ciara931]

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

[@XxGamerGuyxX20011234]

Keep it up Sal, Keep it up!

[@vivconable]

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 :-(

[@bedhathebest3743]

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

Where did you get that blackboard software?

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

[@kdr_roxas]

yep

Thanks so much keep up the good work

[@nadaelnokaly4950]

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

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

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

here before finals

Probably a graphics tablet/pen.

he my homie

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

Hey can someone who is smart help me

I need help too lol

[@bedhathebest3743]

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?

[@jinglin540]

exponential function

((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 (🏫👩🏿‍🏫👨‍🏫👨‍🔬👩‍🔬➕➖✖➗📔📚📝✏🍎❤🎒))).
