1. 4.5 Interpret Graphs of Exponential and Logarithmic Functions
Pg. 149

2. Warm up What are all the terms associated with zeros of a function?
How do you find the intercepts, x and y?

3. Graphs
Exponentials/Logarithmic functions are either increasing or decreasing
Average Rate of change
Slope
Find 2 points and use the slope formula
m = (y2-y1)/(x2-x1)

4. y = 2x - 4 Graph (Make sure you have 3-4 real points)
List Domain/Range
List Zeros
List intercepts
Intervals Increasing/ Dec.
End Behavior
Avg. rate of change from A to B A B

5. y = log2 x Graph (Make sure you have 3-4 real points)
List Domain/Range
List Zeros
List intercepts
Intervals Increasing/ Dec.
End Behavior
Avg. rate of change from A to B A B
