The Answer of Let $f ( x ) = 2 x ^ { 3 } - 3 x ^ { 2 } - 12 x + 13$ . Find all critical points of f and use the second derivative test to classify each as a relative maximum, a relative minimum, or neither.

Let f(x)=2x3−3x2−12x+13f ( x ) = 2 x ^ { 3 } - 3 x ^ { 2 } - 12 x + 13f(x)=2x3−3x2−12x+13

Let $f ( x ) = 2 x ^ { 3 } - 3 x ^ { 2 } - 12 x + 13$
