Answer
Explanation:
Step1: Apply chain - rule
The chain - rule states that if $h(x)=f(g(x))$, then $h^{\prime}(x)=f^{\prime}(g(x))\cdot g^{\prime}(x)$.
Step2: Evaluate at $x = 4$
We need to find $h^{\prime}(4)$, so we substitute $x = 4$ into the chain - rule formula: $h^{\prime}(4)=f^{\prime}(g(4))\cdot g^{\prime}(4)$.
Step3: Find $g(4)$ and $g^{\prime}(4)$ from the table
From the table, when $x = 4$, $g(4)=12$ and $g^{\prime}(4)=-2$.
Step4: Find $f^{\prime}(g(4))$
Since $g(4)=12$, we need to find $f^{\prime}(12)$. From the table, when $x = 12$, $f^{\prime}(12)=-1$.
Step5: Calculate $h^{\prime}(4)$
Substitute $f^{\prime}(g(4))=-1$ and $g^{\prime}(4)=-2$ into the formula $h^{\prime}(4)=f^{\prime}(g(4))\cdot g^{\prime}(4)$. So $h^{\prime}(4)=(-1)\times(-2)=2$.
