Exponential and Logarithm Function GraphsHere you can experiment with the graphs of exponential functions and their inverse logarithm functions for bases b > 0. The large point (labelled "B") on the red exponential graph can be dragged left and right along the graph and you can see its corresponding point (labelled B'), with reverse coordinates, on the inverse logarithmic graph. Note that it's useful to plot the points: (-1, 1/b), (0, 1) and (1,b) on the exponential graph. The reversed coordinates (1/b, -1), (1, 0) and (b,1) will be the corresponding points on the inverse logarithmic graph. Gary Church, Created with GeoGebra |
