Exponential Regression on the TI84 - Example 1

[@RachealBrock]

I was working on a problem for 3 hours until I found your video. I cried happy tears. thank you so much.

[@carlosbarragan2047]

Excellent!
Thanks for explaining the process so clear and simple.

I watched it several times - it was that good.

[@emilywarwick6972]

This made so much sense- thank you!

4:29 it does not let me do my the Regression it says error every time ... i followed ever steps exactly

Do you have the TI-84 Plus. I think the menus are slightly different from the virtual calculator he uses.

[@andrewhampton6599]

really helped with some homework I have. Nice video!

all my numbers come out but I don't get the line.

And if your L2 values are negative?
Example:
L1 = (0, 1, 2, 3, 4) L2 = (-35, -245, -1715, -12005, -84035)
The ExpReg function returns a Domain error. Why?
The scatter plot works, and the equation for this curve is f(x) = (-35)(7)^x

BEST VID EVER

Thanks, it'll help for my quiz. :)

[@Blackjacksys]

Thank you. My math teacher wouldn't tell me how to actually do it when I missed the instructional day.

Glad I could help!

Yesss best explination

[@c0okie_m0nsterrs]

thanks, helped with deltamath

[@ChicoTheHotdog]

helped a lot thanks!

My numbers are slightly off than the ones he has in terms of decimals, even though my table is exactly like his.

Love this video!!!! Is there a powerpoint that my kids could print off with it if not no big deal:)

[@Chewy427]

Ok but how does the calculator do it?

[@Bancho789]

Thank you!

a percentage (fraction) of how accurate this regression is
