For the Polynomial, List Each Real Zero and Its Multiplicity $$f ( x ) = 3 ( x - 6 ) ( x + 7 ) ^ { 3 }$$

Multiple Choice

For the polynomial, list each real zero and its multiplicity. Determine whether the graph crosses or touches the x-axis at
each x -intercept.
- $$f ( x ) = 3 ( x - 6 ) ( x + 7 ) ^ { 3 }$$

A) 6 , multiplicity 1 , crosses $x$ -axis; $- 7$ , multiplicity 3 , crosses $x$ -axis
B) $- 6$ , multiplicity 1 , touches $x$ -axis; 7 , multiplicity 3
C) $- 6$ , multiplicity 1 , crosses $x$ -axis; 7 , multiplicity 3 , crosses $x$ -axis
D) 6 , multiplicity 1 , touches $x$ -axis; $- 7$ , multiplicity 3
