Logarithmic Functions Continued

So today we went over some examples in the unit 4 booklet. There are two types of graphing we learned about in class. We learned how to graph inverse logs and normal logs.

To find an inverse of f(x)=a^x using four steps method:
1-Replace f(x) with y
2-Reverse the roles of x and y
3-Solve for y in terms of x
4-Replace y with f(x)^-1

Here is an example below:

















Normal Log
- To graph a normal log all you do is make the table of values like you do for the others. You first graph the basic points and then you graph the shifted points. This is like unit 2 graphing.

Here is an example below:
