First of all, we can made y value table with random x values. Don't take big numbers, because it will be difficult to drop them on the plane coordinate system. Here is our table: \begin{array}{|c|c|c|c|c|} \hline x & -2 & -1 & 0 & 1 \\\hline y & 0.75 & 1.5 & 3 & 6 \\\hline \end{array} Now we can drop the points from our table on the plane coordinate system and draw graph of exponential function.
