Use the X-Intercepts to Find the Intervals on Which the Graph

Multiple Choice

Use the x-intercepts to find the intervals on which the graph of f is above and below the x-axis.
- $$f ( x ) = ( x - 3 ) ^ { 3 }$$

A) above the $x$ -axis: $( 3 , \infty )$
below the $x$ -axis: $( - \infty , 3 )$

B) above the $x$ -axis: $( - \infty , 3 )$
below the $x$ -axis: $( 3 , \infty )$

C) above the $x$ -axis: no intervals
below the $x$ -axis: $( - \infty , 3 ) , ( 3 , \infty )$

D) above the $x$ -axis: $( - \infty , 3 ) , ( 3 , \infty )$
below the $x$ -axis: no intervals
