\]
\[
v(0) = -1, \quad v'(0) = 2
\]
Find the values of the following derivatives at \( x = 0 \).
(a) \(\frac{d}{dx}(uv)\)
(b) \(\frac{d}{dx}\left(\frac{u}{v}\right)\)
(c) \(\frac{d}{dx}\left(\frac{v}{u}\right)\)
(d) \(\frac{d}{dx}(7v - 2u)\)
**20.** Suppose that \( u \) and \( v \) are differentiable functions of \( x \) and that:
