Question 10. Version 1*/1. Score: 5/5
Let $f(x)$ be a function defined as given in the following table:
\begin{tabular}{|c|c|c|c|c|c|c|}
\hline
$x$ & 0 & 7 & 14 & 21 & 28 & 35 & 42 \\
\hline
$f(x)$ & 0 & 7 & 26 & 46 & 59 & 57 & 42 \\
\hline
\end{tabular}
Estimate the area under the curve of $f(x)$ between the interval $[0, 42]$ using $L_6$, $R_6$ and $M_3$.
