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.f(x) = x3 + x2 - 42x

A. 0, multiplicity 1, crosses the x-axis
7, multiplicity 1, crosses the x-axis
-6, multiplicity 1, crosses the x-axis
B. 0, multiplicity 1, touches the x-axis and turns around;
- 7, multiplicity 1, touches the x-axis and turns around;
6, multiplicity 1, touches the x-axis and turns around
C. 0, multiplicity 1, crosses the x-axis
- 7, multiplicity 1, crosses the x-axis
