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) $\bar { f } ( x ) = 8 x ^ { 3 } - 60 x ^ { 2 } + 200 x$

Quizplus · Accepted Answer

The 5-unit moving average is calculated by averaging the function values over a 5-unit interval. The correct expression for the moving average is $\bar { f } ( x ) = 8 x ^ { 3 } - 60 x ^ { 2 } + 200 x - 250$.
