This is a linear equation which ALWAYS has the domain of the set of all real numbers

Why? Because you can plug in any real number you can think of into x to get some real number out for f(x). There are no restrictions for the input.

Translate that into interval notation to get $\large \color{red}{(-\infty,\infty)}$

It is a polynomial function, so the domain is all real numbers.
