What is the domain of `f(x)=4x^2-x-3` ?
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.
