Are you sure you wrote it right? :-(
The function f(x)=2x-5 is a linear function.
Unless otherwise stated (and that does not seem to be the case) in the real numbers domain, x may assume any value.
The same can be said to y.
So, the lowest output value approached by this function is -∞
(minus infinity).

It would sometimes signify the unity of two separate kingdoms
