In the last few lessons, we have learned a lot about exponential and logarithmic functions. We have learned how to recognize their graphs, and evaluate points on their graphs. We looked at how to manipulate exponential and logarithmic functions, how to switch between them, and when we could not evaluate logs, how to change their bases. Lastly, we looked at the relevance of these functions in our daily lives. We hope you will reviewed the material in both the practice sets and the problem sets. Best of luck to you, we know your going to do well.
