Graphs of Logarithmic Functions (3)

This shows the graphs of exponential functions and logarithmic functions to the same base on the same coordinate plane.
Follow these steps to investigate the graphs:
1. Move the points along the given graph.
2. Check the first box for the graph of exponential function of the same base.
3. Check the second box for the line joining the two points on the two curve.
4. Check the third box for the mid-point joining the two points above.
5. As you trace the mid-point, can you observe the symmetry between the two graphs?
6. Check the fourth box for the axis of symmetry.
