Exponential Function and Logarithmic Function

A Comparison of Two Inverse Functions

When "a" is the base, let's examine the graphs of and 1)   State your opinion about the change by moving the slider. 2) Observe and share the changes in the graphics by moving the slider b. 3) What could be the equation of the symmetry line for these two graphs? After expressing your opinion, please tick the symmetry line box. 4) While the symmetry line is shown, move the sliders and share your observation about the movements of the line and graphics.
TASK: Draw the graph of the function and its inverse function and try to find the equation of the symmetry line.
