Drawing graph of the exponential function

How to draw graph of exponential function? In this topic we will teach you exponential functions drawing technique.

Let's draw example graph of $y=3\cdot 2^x$. 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.
