Q The polynomial f (x) = 5x4 2x3 2x − 7 can have, at most, how many solutions?(Carefulpay attention to multiplicity) Q What does multiplicity of a zero mean?Hi Bryony y = x 2 2x 3 is a parabola Since the x 2 is positive, it opens upward (concaveup) If you factor the right hand side, you get (x1) (x3) so that means that the xintercepts are at 1 and 3 The vertex is halfway between these of course
