Comparing Logarithm and Exponential Functions graphs

1) Change the position of the slider in order to change parameter a which is used as the base of the exponential and the logarithmic functions. Questions: 1. Explain the graphs of the exponential and logarithmic functions. 2. What will happen to the graph if the base (a) is 0? 3. What have you notice to the graph if the base (a)is 1?
