The value of a certain investment over time is given in the table below. Answer the
questions below to determine what kind of function would best fit the data, linear or
exponential.
I
Number of
Years Since
Investment
Made, x
Value of
Investment
(8), f(x)
16,743-49 14.442.68
2
14,442.68 = 2,300.81
2,084.01
S
16,743.49x = 14,442.68
x=0.86
3
16,743.49
14,442.68 12,358.67
Since the change in the table is not constant that means this is a linear function because as x increases, the y value changes
multiplicatively the common difference is approximately:
12.358.67
10,671.14
