Work Step by Step
$R(x)=\sqrt{\frac{13+7x^{0.4}}{1+4x^{0.4}}}$,
a. $R(1)=2,$
$R(10)=337,$
$R(100)=1499.96,$
b. $\begin{array}{ll}
x& R(x)\\
1&2\\
10&337\\
20&516.15\\
30&668.4\\
40&806.6\\
50&935.35\\
60&1057.2\\
70&1173.75\\
80&1285.94\\
90&1394.5\\
100&1499.96
\end{array}$
c. $R(10)=337,$
$R(100)=1499.96,$
$\Delta R=1162.96$
