I'm guessing that you mean f(x) = 2x^2 + 3x +2.
This is a polynomial and all polynomials are defined for all real numbers.
Just ask yourself, is there any number that you can't square and multiply by 2? Is there any number that you can't multiply by 3? Is there any number that you can't just add 2 to it?
Since the answer is no to each of these, there isn't anything that you couldn't plug into f and get a result.
D.

Since there are no values of x that would make f(x) undefined, the domain is all real numbers.

if you meant 2x^2 + 3 x + 2 then the ans is D because there are no vertical assyntopes
