find the inverse:
Y=(x-3.21)(14700 - 3040x)
Answered by Reiny
to find the inverse, interchange the x and y variables, so

x = (y-3.21)(14700 - 3040y)

You have a quadratic function, which is not a one-to-one function, unless the domain is restricted, and it is not here.

Inverses of funcions which are not one-to-one do not exist.
