is the following system invertible?
as I understand it, invertible means finding an inverse function which should return back the original input from an output of the given system.
but for example, If our original input is x + 3 then its derivative is 1,
and if I try to use the inverse function it returns x + c.
is the nature of not knowing what exactly c equals makes the system non-invertible; meaning the original input cannot be restored. Does that make the system non-invertible
