Exponential Function and label the values
- f(x) = b^x
- b-base, constant
- x-exponent, independent variable
Given a exponential function, with no specific x, what do you do?

You input your own values.
Given a exponential function, with no specific x, what do you put your domain as?

"all real numbers"
What does the domain and range represent?
- Domain-x value
- Range-y value
How would you write the domain?
- D-all real numbers
- R- {y|y>0}
Exponential Growth
- f(x) = ab^x, with a>0 and b>1
- The function increases as x increases
Exponential Decay
- 0<b<1
- function dcreases as x increases
Is this a growth or decay function? f(x) = 1.5^x

Growth
Is this a growth or decay function? f(x) = (.8^x)?

Decay
