find the derivative of the square root of (2x^3+4x^2+2x+1)

myininaya (myininaya):

\[y=(f(x))^\frac{1}{2}=>y'=\frac{1}{2}(f(x))^{\frac{1}{2}-1}f'(x)\]

OpenStudy (anonymous):

so it would be ( 6x^2+8x+2) ^1/2?

myininaya (myininaya):

\[f(x)=2x^3+4x^2+2x+1 => f'(x)=6x^2+8x+2\] just plug into what i wrote above

OpenStudy (anonymous):

1/2 ( 6x^2+8x+2)

sorry my calc skills r rusty

myininaya (myininaya):

\[y'=\frac{1}{2}(f(x))^{\frac{1}{2}-1}f'(x)\] i gave you f(x) and i gave you f'(x) just plug those in
