For the Polynomial, List Each Real Zero and Its Multiplicity $$f ( x ) = 4 ( x - 3 ) ( x + 7 ) ^ { 4 }$$

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.
- $$f ( x ) = 4 ( x - 3 ) ( x + 7 ) ^ { 4 }$$

A) 3 , multiplicity 1 , crosses $x$ -axis; $- 7$ , multiplicity 4 , touches $x$ -axis
B) $- 3$ , multiplicity 1 , touches $x$ -axis; 7 , multiplicity 4 , crosses $x$ -axis
C) $- 3$ , multiplicity 1 , crosses $x$ -axis; 7 , multiplicity 4 , touches $x$ -axis
D) 3 , multiplicity 1 , touches $x$ -axis; $- 7$ , multiplicity 4 , crosses $x$ -axis
