Step-by-step explanation:
+2*k*pi is for the periodicity (if you turn 360° you get back to the same point)

OR you could use a graph for this, here is how the function is going to look:
A function that depicts depreciation can be represented as equations, graphs and tables.
<h3>The yearly value of each car for the first five years</h3>The functions are given as:
Where:
C = 5895 --- the initial value of the car
r = 22% --- the rate of depreciation
For the first 5 years, the values of t = 1, 2, 3, 4 and 5
For the first function, we have:
For the second function, we have
So, the table of values is:
See attachment for the graphs of the two functions
<h3>Interpreting the graphs</h3>The graph of car 1 increases up to C(t) = 5895, and then remains constant as the value of t increases while the graph of car 2 follows an exponential pattern.
This means that, the graph 2 that follows an exponential pattern is more realistic
<h3>The worth of the cars after 5 years</h3>From the table, the worth of car 1 is $5892.0, while the worth of car 1 is $1702.0
