Final answer:
The domain of the given function is all real numbers.
Step-by-step explanation:
The quadratic equation is given as follows:
AX = 3x^2 + x + 2
To find the domain of the function, we need to determine the set of all possible values of x that make the function defined. In this case, since we are dealing with a quadratic function, the domain is all real numbers. Hence, the domain of the given function is all real numbers.
