Determine the Inflection Point Of $f ( x ) = 2 x ^ { 3 } - 9 x ^ { 2 } + 12 x - 1$

Short Answer

Determine the inflection point of $f ( x ) = 2 x ^ { 3 } - 9 x ^ { 2 } + 12 x - 1$ Enter your answer exactly as just an ordered pair of fractions: $\left( \frac { \mathrm { a } } { \mathrm { b } } , \frac { \mathrm { c } } { \mathrm { d } } \right)$
