Consider the Following Experimental Results $$\begin{array} { c c c } \text { OBSERVED RF } & \mathrm { M } & \mathrm { MU } \\18.5 \% & 0.46 & 23.1 \\& & \\6.4 \% & 0.137 & 6.8\end{array}$$

Essay

Consider the following experimental results.
(M = mapping function and MU = M x 50)
$$\begin{array} { c c c } \text { OBSERVED RF } & \mathrm { M } & \mathrm { MU } \\18.5 \% & 0.46 & 23.1 \\& & \\6.4 \% & 0.137 & 6.8\end{array}$$
Based on these results,would you advocate the use of mapping functions? In which situations would you recommend using them?
