- The zeros of the function are 0 and 2
- The multiplicity is the power to which the factors are raised. The multiplicities of the function are 1 and 3.
<h3>Zeros and multiplicities of functions</h3>
Given the function 
The zeros of the function is at the point where y = 0

Hence the zeros of the function are 0 and 2
The multiplicity is the power to which the factors are raised. The multiplicities of the function are 1 and 3.
