Find the zeros for the polynomial function and give the multiplicity for each zero. State whether the graph crosses the xaxis or touches the xaxis and turns around, at each zero.
f(x) = 2(x  2)(x + 4)^4
2, multiplicity 1, crosses xaxis; 4, multiplicity 4, touches xaxis and turns around
f(x) = 3(x  3)(x  6)^3
3, multiplicity 1, crosses xaxis; 6, multiplicity 3, crosses xaxis
f(x) = 4(x  5)^3
 2, multiplicity 1, touches the xaxis and turns around; 5, multiplicity 3, touches xaxis and turns around

first two right, last one wrong. How do you get a solution of x=2?

x=32
