Answer
Explanation:
Step1: Recall the chain - rule formula
The chain - rule states that if $h(x)=f(g(x))$, then $h^{\prime}(x)=f^{\prime}(g(x))\cdot g^{\prime}(x)$.
Step2: Find $g(4)$
From the table, when $x = 4$, $g(4)=3$.
Step3: Find $f^{\prime}(g(4))$
Since $g(4)=3$, we need to find $f^{\prime}(3)$. From the table, $f^{\prime}(3)=1$.
Step4: Find $g^{\prime}(4)$
From the table, when $x = 4$, $g^{\prime}(4)=7$.
Step5: Calculate $h^{\prime}(4)$
Using the chain - rule $h^{\prime}(4)=f^{\prime}(g(4))\cdot g^{\prime}(4)$. Substitute $f^{\prime}(g(4)) = 1$ and $g^{\prime}(4)=7$ into the formula. So $h^{\prime}(4)=1\times7 = 7$.
Answer:
$7$
