Graphs of Logarithmic Functions
This shows the graphs of logarithmic functions to the bases a and 1/a on the same coordinate plane (a = 2, 3, 4, 5).
Observe the given graph by doing the following steps.
1. Drag the base to show different movements of the graph.
2. Show the graph of reciprocal base.
Questions:
1. What have you notice of the graph with the base greater than 1 (b>1)?
2. How about with the graph with base less than 1 but greater than 0 (0<b<1)?
3. What are your insights/observation about the graph and its reciprocal?
