Today in class we talked more about Exponential functions, and went through problem 3 from the worksheet we got yesterday.
You can graph Exponential functions in four different ways:

F(x) = ab^2  <—— general equation

The b-value represent the stretch
b > 0
b -> not equal to 1
a -> not equal to 0

Domain/Range
D: all real numbers
R: if a > 0 then y > o
     if a < 0 then y < 0

Symmerty –> None
* no even symetry
* no odd symerty

Increasing/Decreasing
* always increasing or always decreasing
* always one-to-one function

Concavity
If a is positive = concavity up
If a is negative = concavity down

Inflection points:
Its the points where it change from concavity up to concavity down. And Concavity down to concavity up.
