Hello, I have some datas to fit with by the following equation y =
1/(Ax+B) where A and B are the constant coefficients, and I need to
get the values of A and B.
Also I need the plot of the linearized form of the function
which is (1/y)=Ax+B, (X=x and Y=1/y), and the function itself
together.
I really need help with the code. Thank you.

All you have to do is just replace y by (Y=1/y)
rest code will be the same as that of linear regression
I am writing my code in python

Given the differential equation
(ax+b)2d2y/dx2+(ax+b)dy/dx+y=Q(x)
show that the equations ax+b=et and t=ln(ax+b) reduces
this equation to a linear equation with constant coefficients hence
solve
(1+x)2d2y/dx2+(1+x)dy /dx+
y=(2x+3)(2x+4)
4(a). Find the equation y = ax + b of the line passing through
(2,3) and (5,8). (Your answer should be an equation of the form y =
ax + b, for some constants a and b.)
(b) Find the equation y = ax^2 + bx + c of the parabola passing
through the points (-2, -6), (1,6), and (3,4). (Your answer should
be an equation of the form y = ax^2 + bx + c, for some constants a,...
If an SPL ( LINEAR EQUATION SYSTEM ) is known: Ax = b. A is a
matrix sized m × n and b is a vector sized m × 1, with the
component values of matrix A and vector b known. The x vector is n

A power equation is a nonlinear regression equation of the
form
y equals ax Superscript by=axb.
Use a technology tool to find and graph the power equation for
the data below. Include a scatter plot in your graph. Note that you
can also find this model by solving the equation
log y equals m left parenthesis log x right parenthesis plus
blogy = m(log x)+b.
