The piecewise defined function is
f(t) = 800 * 1.5^t for 0 - 2
f(t) = 2700 * 1.05^t-3 for 3 to 9
<h3>How to determine the piecewise functions?</h3>
On the domain of t = 0 to 2, we have:
f(0) = 800
f(1) = 1200
f(2) = 1800
The above function is a piecewise function with the following definition
f(0) = 800 --- initial value
r = 1200/800 = 1.5 --- rate
The function is then represented as:
f(t) = f(0) * r^t
This gives
f(t) = 800 * 1.5^t
On the domain of t = 3 to 9, we have:
f(3) = 2700
f(4) = 2835
The above function is a piecewise function with the following definition
f(3) = 800 --- initial value
r = 2835/2700 = 1.05 --- rate
The function is then represented as:
f(t) = f(3) * r^t-3
This gives
f(t) = 2700 * 1.05^t-3
Hence, the piecewise defined function is
f(t) = 800 * 1.5^t for 0 - 2
f(t) = 2700 * 1.05^t-3 for 3 to 9
