Find the zeros of the polynomial function. State whether the graph crosses the x-axis, or touches the x-axis and turns around, at each intercept. f(x) = (x + 1)(x - 2)(x - 1)2

Question

x = -2, crosses the x-axis;
x = -1, touches the x-axis and turns around
B. x = -1, crosses the x-axis;
x = 2, crosses the x-axis;
x = 1, crosses the x-axis
C. x = 1, crosses the x-axis;
x = -2, touches the x-axis and turns around;
x = -1, touches the x-axis and turns around
D. x = -1, crosses the x-axis;
x = 2, crosses the x-axis;
x = 1, touches the x-axis and turns around
