Multiple Choice

Calculate the 5-unit moving average of the given function. $$f ( x ) = 8 x ^ { 3 }$$

A) $\bar { f } ( x ) = 8 x ^ { 3 } - 60 x ^ { 2 } + 200 x + 250$
B) $\bar { f } ( x ) = 8 x ^ { 3 } + 60 x ^ { 2 } + 200 x - 250$
C) $\bar { f } ( x ) = 8 x ^ { 3 } - 60 x ^ { 2 } + 200 x - 250$
D) $\bar { f } ( x ) = 8 x ^ { 3 } - 60 x ^ { 2 } - 250 x + 200$
E) $\bar { f } ( x ) = 8 x ^ { 3 } - 60 x ^ { 2 } + 200 x$
