Q. The functions p(x) and q(x) are differentiable. The function v(x) is defined as: v(x)=q(x)p(x) If p(8)=4, p′(8)=2, q(8)=3, and q′(8)=−1, what is v′(8)? Simplify any fractions. v′(8)=
Identify the rule: Identify the rule for differentiating a quotient.The quotient rule for differentiation states that if v(x)=q(x)p(x), then v′(x)=(q(x))2p′(x)q(x)−p(x)q′(x).
Apply the quotient rule: Apply the quotient rule using the given values.We have p(8)=4, p′(8)=2, q(8)=3, and q′(8)=−1. Plugging these into the quotient rule, we get:v′(8)=(q(8))2p′(8)q(8)−p(8)q′(8)v′(8)=322⋅3−4⋅(−1)
