Given the function:

`f(x)= 4x^2 - x - 3`

We need to find the domain of the function f(x).

The rule of the domain of polynomial is clear.

If the function is a polynimial, then, the domain is all real numbers because we do not have any restrictions on the values of x.

Then, the domain of f(x) is all real numbers.
