Suppose That X and Y Are Related by the Equation $x ^ { 3 }$

question 21

Multiple Choice

Suppose that x and y are related by the equation $x ^ { 3 }$ + $( 2 y + 1 ) ^ { 2 }$ = $y ^ { 2 }$ . Use implicit differentiation to determine $\frac { d y } { d x }$ .

• A) \(\frac { d y } { d x }\) = \(\frac { 3 x ^ { 2 } + 4 ( 2 y + 1 ) } { 2 y }\)
• B) \(\frac { d y } { d x }\) = 3 \(x ^ { 2 }\) + 2(y + 1)
• C) \(\frac { d y } { d x }\) = \(\frac { - 3 x ^ { 2 } } { 2 ( 3 y + 2 ) }\)
• D) \(\frac { d y } { d x }\) = \(\frac { - 3 x ^ { 2 } } { 6 y + 1 }\)
