Name __________________________________________ Lesson #1: Exponential Functions and Their Inverses Algebra II with Trigonometry Unit 8: Logarithmic Functions .
Recall: The function log is the name we give the inverse of For example, log is the inverse of
2 . We can write an equivalent exponential equation for each logarithm as follows: log
⟺
Recall:
⟺
These two equations are equivalent
if
0 and
0, (
1).
Remember: A logarithm IS an exponent.
: exponent
: base
: “answer”
Important!
You must be able to go back and forth between equivalent logarithmic & exponential forms!
