1. 4.4 Graph Exponential Growth Functions

2. Vocabulary
Exponential Function: y = abx, where a ≠ 0 and the base b is a positive number other than 1.
Examples:

3. Exponential Growth & Decay
y = abx

4. Vocabulary
asymptote: line that the graph approaches more and more closely, but does not touch or cross

5. Vocabulary
end behavior of a function’s graph: the y-behavior of the graph as x approaches positive or negative infinity.

6. Graphing y = bx
Graph y = 4x
X Y -2 -1 1 2

7. Graphing y = abx
Graph
X Y -1 1

8. Graphing y = abx
Graph
X Y 1 2

9. Graphing y = abx-h+k Translates the graph left 2 units
down 1 unit

10. Graphing y = abx-h+k
