Answer:
Exponential growth function--
- [tex]A=20,000(1.08)^t[/tex]
( Since, 1.08>1)
( Since, 3>1)
- [tex]P=1700(1.07)^t[/tex]
( Since, 1.07>1)
Exponential decay function--
- [tex]A=80(\dfrac{1}{2})^t[/tex]
( Since, 1/2=0.5<1)
( Since, 0.8<1)
- [tex]P=1700(0.93)^t[/tex]
( Since, 0.93<1)
Step-by-step explanation:
We know that the general exponential function is given by:
[tex]y=ab^x[/tex]
where a is the initial amount.
and if b>1 then the function represents a exponential growth function.
and 0<b<1 then the function represents a exponential decay function.
