Let's graph
What would it's inverse look like?
What are the asymptotes, domain, & range of the original function & it's inverse?
15
If the main points on a graph for the exponential function y = bx are (0, 1) & (1, b),
then what are the main points on the graph of the logarithmic function y = logbx ?
