finding non linear function between two values

[jane83]

i have 2 set of data
1st set 2nd Set
1.25------ 1.25
1.3------- 1.4
1.4------- 1.66
1.5------- 1.885
1.6------- 1.925
1.7-------- 1.95
1.8------- 1.975
1.9-------- 2
2---------- 2.04
2.1------- 2.11
2.2------- 2.2

i want to find the relationship between the two sets

Plug the data they gave you into whatever software you're supposed to use (Excel, your graphing calculator, etc), and find the required regression line.

Please share with us your work, and exactly where you are stuck - so that we know where to begin to help you.

First plot these numbers - and decide what type of relationship you will be satisfied with.

There are two distinct regions in this data set. It will be better - depending on where it is being used - to seek two different functions (for those two domains).

thanks for the help...
i just tried it with Matlab curve fitting tool and got the equations...
