We do not have a `log_2 x` button on our calculators. The only way we can do this for now is to draw up a table of values and plot the points, or use a computer.
Later we will see how to plot this using the change of base formula which we meet in 5. Logs to the Base e.
Using a computer to graph it gives us:
Graph of `y=3log_2 x`.
Unlike the graph in the previous example, this graph does not have a limiting value as x increases.
