1. Ch. 4.4 to 4.5

2. “a” changes the steepness of the growth or decay If (-a) graph is flipped “b” is the base it determines if it is an EXPONENTIAL GROWTH (greater than 1) or EXPONENTIAL DECAY (fraction or decimal between 0 and 1) “k” is the horizontal asymptote moves the graph up or down

4. Step 1: Determine if the graph is Exponential Growth or Decay Exponential Growth: Exponential Decay: Step 2: Find the asymptote: graph as a dotted horizontal line Step 3: Find the y-int – plug in a zero for x

5. Domain for Exponential is always ALL REAL NUMBERS Range: if a is positive it is y>k (asymptote) if a is negative it is y<k (asymptote) A negative a-value will flip the graph: Example: This is the graph of

6. FIND THE LENGTH OF THIS #19)
