Basic Graph of a Logarithmic Function

This illustrates the graph of a function log x where b is the base. Adjust the slider to adjust the value of b.[br]1. What happens when b > 1? What happens as b increases and is larger than 1?[br]2. What happens when b<1? What happens as b approaches 0?[br]3. How does changing b affect the x-intercept? Why?
