Suppose U and V Are Differentiable Functions of X $$u ( 1 ) = 4 , u ^ { \prime } ( 1 ) = - 7 , v ( 1 ) = 6 , v ^ { \prime } ( 1 ) = - 3 \text {. }$$

Multiple Choice

Suppose u and v are differentiable functions of x. Use the given values of the functions and their derivatives to find the value of the indicated derivative.
