(a) Show that the derivative of \( y = 12 x - x ^ ...

(a) Show that the derivative of \( y = 12 x - x ^ { 3 } \) is \( y ^ { \prime } = 3 ( 2 - x ) ( 2 + x ) \) . 

(b) Use a table of values of \( y ^ { \prime } \) to show that there is a maximum turning point at \( ( 2,16 ) \) 

and a minimum turning point at \( ( - 2 , - 16 ) \) . 

(c) Sketch a graph of the function, showing all important features. 

Answer

(2,16) (-2,-16)

-\(2\sqrt{3} \)
