With each quadratic polynomial x^2 + ax + b with real coefficients, associate the smaller of its two real zeros. Is this association a function? If this association is not a function, explain why. If this association is a function, find its natural domain and explain how to tell from the coefficients a and b whether a polynomial x2 + ax + b is in the domain.
