Exponential Regression on the TI84 - Example 1 

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

I watched it several times - it was that good.

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

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

This made so much sense- thank you!

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

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

thanks, helped with deltamath

BEST VID EVER

helped a lot thanks!

Yesss best explination

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

a percentage (fraction) of how accurate this regression is

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:)

Thank you!

Ok but how does the calculator do it?
