In this problem, assume that you are given data (

_i
,


_i
), with

= 1, 2, ,
, and a nonlinear model function
() that contains two parameters:

₁
and

₂. The objective is to find a change of variables from (,
) to (,

) so the transformed model function has the form
() =

₁
+
₂
. Find a change of variables that accomplishes this for the following model functions, give the resulting solution for

₁
and

₂, and the corresponding solution for

₁
and

₂.
