Key concepts
3 concepts
- 1
The parent function for exponential functions is y = a * bˣ, where 'a' represents the starting value (y-intercept) and 'b' represents the growth rate.
- 2
For a growth function, the growth rate (b) must be greater than one, while for a decay function, the growth rate (b) must be between zero and one.
- 3
In the exponential function y = 5 * 0.25ˣ, the start value is 5 and the growth rate is 0.25, indicating a decay function.
