Essay

Following are approximate values of the Amex Gold BUGS Index. $\begin{array} { | l | l | l | l | } \hline \text { Year } \boldsymbol { x } & 0 & 2 & 4 \\\hline \text { Index } \boldsymbol { y } & 50 & 100 & 250 \\\hline\end{array}$ ​
( $x = 0$ represents 2000)
Complete the table. $$\begin{array} { | l | l | l | l | l | } \hline & x & y & x y & x ^ { 2 } \\\hline & 0 & 50 & & \\\hline & 2 & 100 & & \\\hline & 4 & 250 & & \\\hline \text { Totals } & & & & \\\hline\end{array}$$ ​
