1. BELLWORK >>>Assignment from last class is due if you did not turn it in (12 problems from last slide of Intro to Logs PowerPoint) Problemabhkasymptote (y=k) point #1 (h, a+k) point #2 (h+1,ab+k) y= 3 x-1 1) Fill in the table for the indicated problem and SKETCH a graph! 2) Find the inverse of f(x)=5 x+3 -1

2. OPEN NOTES QUIZ OVER INVERSES Any quick questions before we begin? -Find inverse from a table -Find inverse from a graph -Find inverse from an equation -Know when no inverse exists -Determine if an inverse is a function based on the graph (relationship with one-to-one)

3. RECALL… When a variable is in the exponent, we rewrite as a logarithm in order to solve…

4. SOLVING EXPONENTIAL AND LOGARITHMIC PROBLEMS A few things to note… Change of Base Formula

5. SOLVING EXPONENTIAL AND LOGARITHMIC PROBLEMS Some simple examples: a) b) c) 3 to what power equals 27? d) 1/5 to what power equals 25?

6. SOLVING EXPONENTIAL AND LOGARITHMIC PROBLEMS e) f)
