The equation given:
[tex]u(x)=h(\sqrt[]{x})[/tex]
We need to find u'(4).
This means you put in "4" into the function and see:
So, it becomes:
[tex]\begin{gathered} u(4)=h(\sqrt[]{4}) \\ u(4)=h(2) \end{gathered}[/tex]
Now, we want u'(4), so we need h'(2).
Looking into row and column of table, we find
h'(x) and "2" ------------>> we get "2".
Hence,
[tex]u^{\prime}(4)=2[/tex]
