1. Exponential Functions
x is an exponent
Note: as x increases (going L to R), y increases
They are said to be increasing functions

2. How about f(x) = ( )
we don't have fractional base
reflect over the y-axis
A fractional base results in a decreasing function

3. Characteristics of Exp. Functions
ie. y = b
Domain: (- , )
Range: y > 0
Asymptotes: y = 0 ie. H.A.
Increasing: b > 1
Decreasing: 0 < b < 1

4. Graph:
Use y = 2 as base graph

7. y = -3 · 2
