    if ß is a zero of a polynomial, then (x-ß) is a factor of the polynomial so in this case [x - 7] and [x - (-4)] i.e. [x + 4] are the factors of the polynomial so the polynomial p(x) = [x - 7][x + 4] = x² - 7x + 4x - 28 = x² - 3x - 28 no this function is not unique because all polynomials of the form k(x² - 3x - 28), where k is a real number, will have the same zeros and hence there can be infinite such functions...
