Write the Function in the Form Y = F(u) and U

question 272

Multiple Choice

Write the function in the form y = f(u) and u = g(x) . Then find dy/dx as a function of x.
- $$y = ( - 2 x + 11 ) ^ { 5 }$$

• A) \(y = u ^ { 5 } ; u = - 2 x + 11 ; \frac { d y } { d x } = - 10 ( - 2 x + 11 ) ^ { 4 }\)
• B) \(y = 5 u + 11 ; u = x ^ { 5 } ; \frac { d y } { d x } = - 10 x ^ { 4 }\)
• C) \(y = u ^ { 5 } ; u = - 2 x + 11 ; \frac { d y } { d x } = - 2 ( - 2 x + 11 ) ^ { 5 }\)
• D) \(y = u ^ { 5 } ; u = - 2 x + 11 ; \frac { d y } { d x } = 5 ( - 2 x + 11 ) ^ { 4 }\)
