The following table shows Alexandra's investment options over the course of three years. Her initial investment was $1000.
Number of years
1
2
3
Option 1 (amount in dollars) 1,100 1,200 1,300
Option 2 (amount in dollars) 1,100 1,210 1,331
Write one function for each option to describe the value of the investment f(n), in dollars,
after n years.
The function for Option 1 is:
The function for Option 2 is:

d

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
