Part B: Write one function for each option to describe the value of the investment f(n), in dollars, after n years. (4 points) Number of years 1 2 3
Option 1 (amount in dollars) 1100,1210,1331
Option 2 (amount in dollars) 1100 ,1200,1300

Option 1:

f(n) = 1000(1.1)ⁿ

Option 2:

1000 + 100n

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
