y = x^2
a. all real numbers
b. all positive numbers
c. all negative numbers
d. all real numbers except 0

The correct option is A. The domain of the parent function y=x² is all real numbers.

Step-by-step explanation:

The domain of a function is the set of all possible inputs for which the given function is defined.

The given parent function is

It is a second degree polynomial. It is defined for all the real values of x. So, the domain of the function is all real numbers.

Therefore the correct option is A.
