  1. Warm up • Solve for x: • 1. 53 − 2x =5−x • 2. 32a=3−a • 3. 31 − 2x= 243

  2. Lesson 10-2 Logarithmic Functions Objective: To learn to use both natural & common logarithmic functions.

  3. Logarithmic Functions Logarithms were originally developed to simplify complex arithmetic calculations.

  4. Definition of Logarithm Suppose b>0 and b≠1, there is a number ‘y’ such that: If and only if
