Not sure any more exactly how to do this on the calculator, but make one member a function, make the other member another function, and choose to view a table or a graph of the two functions at the same time. Try TRACE (not sure) to find where the two functions meet.

Example, Y1=2^x-8, and Y2=3x+5.

You will need to pick the right window settings to see everything you need for the graph, and also choose the right zoom level.
