The multiplicity of a zero at which the graph touches the x-axis and then turns back is typically an even number. Therefore, in the provided options, the multiplicities that fit this description would be:
- 2 (which means the graph touches the axis and turns back)
The answer is 2.
Multiplicity of 3 would indicate that the graph crosses the x-axis, not just touches it, and a multiplicity of 0 is not applicable since it doesn’t correspond to any valid zero.
