The given function is a linear function that decreases as the value of the
input <em>x</em> increases.
- The value of f(10), given f(x) = 9 - 2·x is option <u>A. -11</u>
Reasons:
The given function is f(x) = 9 - 2·x
The output of the function is the value of f(x) for a given input <em>x</em> of the function.
The input value, <em>x</em> is substituted into the function to obtain the output value, f(x).
Given that the input, x = 10
We have;
f(10) = 9 - 2×10 = -11
Therefore, the correct option for f(10) is <u>A. -11</u>

Using compound interest, it is found that $20,581.36 will be in the account in 5 years.
<h3>What is compound interest?</h3>
The amount of money earned, in compound interest, after t years, is given by:

In which:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
- t is the time in years for which the money is invested or borrowed.
In this problem:
- The initial deposit is of P = 19000.
- The rate is of r = 0.016.
- Monthly compounding, hence n = 12.
Then:



$20,581.36 will be in the account in 5 years.
