1. Warm-up
Evaluate: 34
4-2
Evaluate each expression for x = 2 x5
5-x

2. Exponential Function Base and Multiplier Example: f(x) = 2x
What were 2 names that we gave the number 2 in this expression?
Base
and
Multiplier

3. Each year the local country club sponsors a tennis tournament
Each year the local country club sponsors a tennis tournament.  Play starts with 128 participants.  During each round, half of the players are eliminated.  How many players remain after 5 rounds?

4. Exponential Functions

5. Think about it…
Linear, Quadratic or Exponential?

6. Growth or Decay?
When b > 1 , the function f(x) = bx represents exponential growth.
When 0 < b < 1, the function f(x) = bx represents exponential decay.

7. Growth or Decay?

8. Graphs:
Both graphs approach the x-axis but never reaches it…we call the x-axis an asymptote.

9. P. 131 do #’s 1-3 with a partner.
Use your calculator to graph. Sketch it on your paper making sure you identify the asymptote.
Identify the Domain and Range.
