Study Notes
Exponential Functions
- An exponential function is defined as ( y = ab^x ), where ( a ) is the initial value, ( b ) is the base (growth or decay factor), and ( x ) is the exponent.
Growth Factor
- A growth factor occurs when the base ( b ) is greater than 1 (( b > 1 )).
- The output of the function increases as ( x ) increases.
Decay Factor
- A decay factor happens when the base ( b ) is between 0 and 1.
- The output of the function decreases as ( x ) increases.
