Best ResponseYou've already chosen the best response.0ok so look at the y values you go from +2, +5, +3, +7, etc...what type of pattern do you think it is?

Best ResponseYou've already chosen the best response.0i mean you go from 112 to 114 by adding 2 etc

Best ResponseYou've already chosen the best response.0im not sure i dont know how to do this problem

Best ResponseYou've already chosen the best response.0ok well i would define it as a piecewise function actually hold on.........hmmmm let me think about this

Best ResponseYou've already chosen the best response.0were looking for a regression equation such as exponential linear or logarithmic

Best ResponseYou've already chosen the best response.0yeah i know...i was just seeing if you could possibly use two different ones and define them only for when x is odd and another for when x is even...

Best ResponseYou've already chosen the best response.0yeah i thought it was exponential and linear but i'm not sure..

Best ResponseYou've already chosen the best response.0its definitely not log

Best ResponseYou've already chosen the best response.0idk..its not perfect linear...

Best ResponseYou've already chosen the best response.0i would just say linear because there is no way to fit it to log or exp

Best ResponseYou've already chosen the best response.0how do you put this in the calculator i don't know how to

anonymous

Best ResponseYou've already chosen the best response.0what calculator do you have?

anonymous

Best ResponseYou've already chosen the best response.0ok so turn it on go to stat go to edit you'll see like L1, L2, etc in L1 put in your x values and in L2 put the y values then quit do 2nd, Y= go to 1: go On then go zoom, go zoomfit

Best ResponseYou've already chosen the best response.0haha i know now you can fit the graph

Best ResponseYou've already chosen the best response.0ok so you want to go stat go to calc go to linreg(ax+b) then put L1, L2 after in the main screen

Best ResponseYou've already chosen the best response.0what do u mean main screen

anonymous

Best ResponseYou've already chosen the best response.0the main screen is where you do all the math...like would do cos(30), 5+1, sqrt(9)...

Best ResponseYou've already chosen the best response.0when you click lin reg(ax+b) it will take you to the main screen

Best ResponseYou've already chosen the best response.0well after i hit lin reg then what

Best ResponseYou've already chosen the best response.0press 2nd 1 , 2nd 2 enter you get a linear regression y = 4.2x + 106.6

anonymous

Best ResponseYou've already chosen the best response.0did you enter it right? hmm........ press 2nd 0 scroll to actually no...that should not be correct

anonymous

Best ResponseYou've already chosen the best response.0okk what do i do now..

anonymous

Best ResponseYou've already chosen the best response.0justify its linear...haha what stat is this for?

anonymous

Best ResponseYou've already chosen the best response.0noo but shouldnt there be a line going through those points ?

anonymous

Best ResponseYou've already chosen the best response.0yeah but look at the graph... do you know the concept of a floor? its like the greatest integer function...and then add like one to it...that should make it approximate. idk unless it has to be regression....then you could try exponential shifted way up...but its the 4th term that makes me question that possibility...

Best ResponseYou've already chosen the best response.0do i plug the linear regression into y=?

anonymous

Best ResponseYou've already chosen the best response.0yeah the equation is supposed to be an approximate for the data

anonymous

Best ResponseYou've already chosen the best response.0but both the linear regression and exponential equations lie in the same place?

anonymous

Best ResponseYou've already chosen the best response.0when i plug the linear regression equation into the y= i end up with a line going across the graph and then when i plug in the exponential regression into the y= the line lays in the same place as the linear regression equation line

Best ResponseYou've already chosen the best response.0is your data correct? idk but i gotta go so when is this due? monday? i can try to help you tomorrow or something...

anonymous

Best ResponseYou've already chosen the best response.0107.1678132(1.035666278^x) is tht the expreg?
