The Quotient rule for calculating the derivative.

The Attempt at a Solution

The derivative f'(x) = (x+5)-(x+3) / (x+5)^2
I tried a previous similar problem but failed as I didn't and still don't know what '' means.

$f''(x)$ is the derivative of $f'(x)$.

 

[gleem]

f^"(x) is the second derivative of f(x)
