Question

How do you find the domain of the function `g(x) = 2/3-5x`?

Answer 1

Domain: all the real `x`.

Explanation:

This is a Linear function that accepts all the real values of `x`.
So, the domain is all the real `x`.
You can have a look at your function graphically as:
graph{(2/3)-5x [-10, 10, -5, 5]}
