transforming the polynomial variable

[Sam Mathew]

Hi,

Given a polynomial function, how can one find another polynomial function
which is obtained by translating the variable by a constant parameter.

For e.g., if,
Velocity = 2 + 3*x + 5*x^2,

if the origin is shifted to say, (2,3), in the positive direction, i.e., x
is to be replaced by x-2; is there a built-in function for finding the
Velocity function (in polynomial form) in the new coordinate system? Is it
possible to extend it to polynomials in two variables?

Is it possible to also perform such transformations if a function is of two
variables x and y, and the coordinate axes undergo different transformations
(translation, rotation, etc.).

Thanks and regards,

Sam
