question 102

Multiple Choice

Differentiate.
-h(x) = $\frac { 5 } { x ^ { 3 } - 4 x ^ { 2 } + 2 }$

• A) h'(x) = \(\frac { 15 x ^ { 2 } - 40 x } { x ^ { 3 } - 4 x ^ { 2 } + 2 }\)
• B) h'(x) = \(\frac { 3 x ^ { 2 } - 8 x } { \left( x ^ { 3 } - 4 x ^ { 2 } + 2 \right) ^ { 2 } }\)
• C) h'(x) = \(\frac { - 15 x ^ { 2 } + 40 x } { \left( x ^ { 3 } - 4 x ^ { 2 } + 2 \right) ^ { 2 } }\)
• D) h'(x) = \(\frac { 5 } { \left( 3 x ^ { 2 } - 8 x \right) ^ { 2 } }\)
