5. For the functions: f(x) = x3 - 4x2 and also f (x) = 2(x2 - 1) (x + 2)2 a) Use the Lead Coefficient Test to find the end behavior of the function. b) Find the zeros for the polynomial function and give the multiplicity for each zero. State whether the graph crosses the x-axis or touches the x-axis and turns around at each zero
