The red graph is the result of a vertical translation, 4 units down, of the black graph.
This means that, whenever the black graph associates
The red graph must associate 4 less to the same input:
So, the equation for the red graph is
or, equivalently,
The amount of interest Molly will earn after 5 years on a deposit of compounded annually over 5 years is
First, we need to find the future value of her investment, then we subtract the original deposit from it to get the amount of interest she will get at the end of 5 years.
The future value of an investment that is compounded annually is given by
where
Substituting the available values into the formula and solving
The interest Molly will earn after 5 years is
Therefore, the amount of interest Molly will earn after 5 years on a deposit of compounded annually over 5 years is
