Respuesta :
The values of b in an exponential function for the changes desired are given as follows:
- 23% decrease: 0.77.
- 8% increase: 1.08.
- 15% decrease: 0.85.
- 120% increase: 2.2.
What is an exponential function?
An exponential function is modeled by:
[tex]y = ab^x[/tex]
In which:
- a is the initial value.
- b is the rate of change.
The rate of change has the following format:
[tex]b = 1 \pm r[/tex]
In which a decrease has a - sign and an increase has a + sign. Hence the changes are given as follows:
- 23% decrease: 0.77.
- 8% increase: 1.08.
- 15% decrease: 0.85.
- 120% increase: 2.2.
