Given f ( x ) = 2 x 3 + 4 x 2 x 2 3 x 4 , which can be written in factored form as f ( x ) = 2 x 2 ( x + 2 ) ( x + 1 ) ( x 4 ) , answer the following questions. Provide the location of any removable discontinuities. [If there are none, enter "DNE".] x = Determine the value of the vertical intercept. y = List all of the horizontal intercepts. [If there is more than one, enter your answer as a comma-separated list.] x = What is the function's end behavior? As x , f ( x ) Provide the locations of any vertical asymptotes. [If there is more than one, enter your answer as a comma-separated list. If there are none, enter "DNE".] x = Use a graphing calculator to graph f and check your answers
