Graph multiple functions Two graph multiple functions we start with a chart that has the input and the output of the multiple functions, Select the column for the input and the outputs to be graphed and then insett a scatterplot. If the input variable is not included, Excel will interpret the first output varaiable as the input and give a very different graoph. If the input and functions are not next to each other in the table, you need to right click (control-click on a Mac) to select cells that are not adjacent.

Use a secondary axis. If the scales of the graphs are noticably differnt we want to use a secondary axis for one of the graphs. For example is we are graphung \(f(x)=x^2\) and \(g(x)=x^5\) for the interval \([-10,10]\text{,}\) the scale of \(g(x)\) is so large that we cannot see what happens fith \(f(x)\text{.}\) To use a secondary axis, double click a point and then select secondary axis from the axes tab.

Formatting a chart. 1.4.5 Excel gives you the ability to format your chart. Clciking on a chart brings up the "Chart Design" tab. There are menus for "Add Chart Element", "Quick Layout", and "Change Chart Type".
