Question

Can someone let me know if I set the derivative of this problem up right...

Answer 1

\[y = 1 / \sqrt{x + 2}\]

Answer 2

do you want to derivate that?

Answer 3

I'm trying to figure that out, I just want to make sure I set it up right. Hold on I'm posting it right now

Answer 4

−1/(2(x+2)^(3/2))

Answer 5

Opps I meant using the chain rule, here's what I got so far:

\[y = (x+ 2) ^{1/2} - 1 (1/2)(x+2)^{-1/2}(1)/(x+2) \]

Answer 6

Can you show me how you got that?

Answer 7

U don't need the chain rule because the derivative of x + 2 is 1, just do it normally.

D -1/2 (x+2) ^ (-3/2) = 3/4 (x+2)^(-5/2)

Answer 8

agree with estudier

Answer 9

okay thanks
