If H(x) = √(r(x)), and r(3) = 9, and r'(3) = -1, What is H'(3)? I used the chain rule but for some reason I'm still getting the wrong answer.

Question

If H(x) =
`√(r(x))`,

and r(3) = 9,
and r'(3) = -1,
What is H'(3)?

I used the chain rule but for some reason I'm still getting the wrong answer.

Answer 1

You should find the answer from the answers you wrote

Explanation:

u should find the x from the answers you wrote like the r'(3) = -1

then from this answer u should think about the h'(3)' answer
