The domain of a quadratic is all real numbers.
a) True
b) False

Step-by-step explanation:

I'd be very hesitant to say true.

If the quadratic is in the form of y = x^2 then the statement is correct. The entire family all have a domain of all the real numbers.

However if the quadratic is of the form x=y^2 then the starting point of this quadratic is (0,0). All of these quadratics have a different starting point. \\

Since you have not specified the kind of quadratic, the answer is not always true.
