Find the Zeros of the Polynomial Function and State the Multiplicity

Multiple Choice

Find the zeros of the polynomial function and state the multiplicity of each.
- $$f ( x ) = 5 x ( x - 7 ) ^ { 3 } \left( x ^ { 2 } - 16 \right)$$

A) 0 (multiplicity 1) , $- 16$ (multiplicity 2 ) , 7 (multiplicity 3 )
B) 0 (multiplicity 1) , $\pm 4$ (multiplicity 1) , 7 (multiplicity 3)
C) $\pm 4$ (multiplicity 1) , 7 (multiplicity 3 )
D) 0 (multiplicity 1 ) , $\pm 4$ (multiplicity 2 ) , $- 7$ (multiplicity 3 )
