1. Day 42: November 5 th Objective: Apply strategies for finding inverses to parent graph equations. Begin to think of the inverse function for y=3 x. THEN Define the term logarithm as the inverse exponential function or, when y=b x, “y is the exponent to use with base b to get x.” Homework Check 6-54 to 6-58 (pgs 277-279) Wells Time 6-67 to 6-71 (pgs 281-282) Closure Homework: 6-59 to 6-66 (pgs 279-280) AND 6-72 to 6-80 (pgs 283-284) Project Due: Monday, November 8 th

5. Logarithm's Undo Exponentials Log’s give you exponents! Inverses Same as

6. Logarithm and Exponential Forms y = log 2 (32) 2 y = 32

7. Logarithms The logarithm base a of b is the exponent you put on a to get b. i.e. Logs give you exponents! a > 0 b > 0
