Janet has money invested in two different accounts. The function [tex]\( f(x) \)[/tex] represents the amount of money in an account after [tex]\( x \)[/tex] years of interest compounded monthly, while the function [tex]\( g(x) \)[/tex] represents the amount of money in an account after [tex]\( x \)[/tex] years of simple interest.

To find the difference in the value of Janet's accounts for each year, we need to calculate the difference between the amounts provided by the functions [tex]\( f(x) \)[/tex] and [tex]\( g(x) \)[/tex] for each year [tex]\( x \)[/tex]. Here are the steps:

1. Identify the values of [tex]\( f(x) \)[/tex] and [tex]\( g(x) \)[/tex] for each year.
2. Calculate the difference [tex]\( f(x) - g(x) \)[/tex] for each year.

Let's proceed step-by-step.

### Step 1: Identify the Values

For [tex]\( x = 1 \)[/tex]:
- [tex]\( f(1) = 1576.74 \)[/tex]
- [tex]\( g(1) = 1575 \)[/tex]

For [tex]\( x = 2 \)[/tex]:
- [tex]\( f(2) = 1657.41 \)[/tex]
- [tex]\( g(2) = 1650 \)[/tex]

For [tex]\( x = 3 \)[/tex]:
- [tex]\( f(3) = 1742.21 \)[/tex]
- [tex]\( g(3) = 1725 \)[/tex]

For [tex]\( x = 4 \)[/tex]:
- [tex]\( f(4) = 1831.34 \)[/tex]
- [tex]\( g(4) = 1800 \)[/tex]

### Step 2: Calculate the Differences

For [tex]\( x = 1 \)[/tex]:
[tex]\[ f(1) - g(1) = 1576.74 - 1575 = 1.74 \][/tex]

For [tex]\( x = 2 \)[/tex]:
[tex]\[ f(2) - g(2) = 1657.41 - 1650 = 7.41 \][/tex]

For [tex]\( x = 3 \)[/tex]:
[tex]\[ f(3) - g(3) = 1742.21 - 1725 = 17.21 \][/tex]

For [tex]\( x = 4 \)[/tex]:
[tex]\[ f(4) - g(4) = 1831.34 - 1800 = 31.34 \][/tex]

Now, complete the table with the calculated differences:

\begin{tabular}{|c|c|c|c|c|}
\hline [tex]$x$[/tex] & 1 & 2 & 3 & 4 \\
\hline Difference [tex]\( f(x) - g(x) \)[/tex] & 1.74 & 7.41 & 17.21 & 31.34 \\
\hline
\end{tabular}

Thus, the differences in the value of the accounts for each year are as shown in the table above:
- For year 1: [tex]$1.74 - For year 2: $[/tex]7.41
- For year 3: [tex]$17.21 - For year 4: $[/tex]31.34
