For the polynomial, list each real zero and its multiplicity. Determine whether the graph
crosses or touches the r-axis at each z-intercept. f(x) = 3(x + 6)(x + 5)“.
(a) 6, multiplicity 1, touches z-axis; 5, multiplicity 4, crosses I-axis
(b) -6, multiplicity 1, crosses z-axis; 5, multiplicity 4, crosses z-axis
(C) 6, multiplicity 1, crosses z-axis; 5, multiplicity 4, touches z-axis
(d) 6, multiplicity 1, touches I-axis; 5, multiplicity 4, touches x-axis
(e) -6, multiplicity 1, touches z-axis; -5, multiplicity 4, crosses z-axis
(f) -6, multiplicity 1, crosses z-axis; -5, multiplicity 4, touches I-axis
