Explanation: The sum of the multiplicities must be . n . Starting from the left, the first zero occurs at =−3. x = −3. The graph touches the x-axis, so the multiplicity of the zero must be even. The zero of −3 −3 has multiplicity 2. 2. The next zero occurs at =−1. x = −1. The graph looks almost linear at this point. This is a single zero of multiplicity 1. The last zero occurs at =4. x = 4. The graph crosses the x-axis, so the multiplicity of the zero must be odd. We know that the multiplicity is likely 3 and that the sum of the multiplicities is likely 6.
