# Suppose h =f\circ g . Find h'(0) given that f(0) = 4, f '(4) = -7,\;g(0) = 4 , and g '(0)...

## Question:

Suppose {eq}h =f\circ g {/eq}. Find {eq}h'(0) {/eq} given that {eq}f(0) = 4, f '(4) = -7,\;g(0) = 4 {/eq}, and {eq}g '(0) = 1. {/eq}

## Chain Rule:

We apply chain rule if we are asked to evaluate the derivative of a composite function.

Suppose we are given the composite function {eq}f(g(x)) {/eq}.

Applying the chain rule:

{eq}D_x(f(g(x)) = f'(g(x))g'(x) {/eq}

First, we calculate {eq}h'(x) {/eq} by applying the chain rule:

{eq}\begin{align*} h(x)& =(f\circ g)(x) \\ h(x)& =f(g(x)) \\ h'(x)&...
