**Find the value of (f ∘ g)' at the given value of x.**

f(u) = (u-1)/(u+1), u = g(x) = , x = 49

To find the value of \((f \circ g)'\) at \(x = 49\), we need to apply the **chain rule**, which states:

\[
(f \circ g)'(x) = f'(g(x)) \cdot g'(x)
\]

### Steps:

1. **Define the functions**:
   - \( f(u) = \frac{u-1}{u+1} \)
   - \( g(x) \) is missing in the problem. To proceed, I will need the explicit form of \(g(x)\).

Can you please provide the function \(g(x)\)?
