Answer: 
Step-by-step explanation:
<u>Given function expression</u>
f(x) = -5x² - x + 20
Requirement of the question
Find the value of f(3)
<u>Substitute the values into the function</u>
f(x) = -5x² - x + 20
f(3) = -5(3)² - (3) + 20
<u>Simplify the exponents</u>
f(3) = -5(9) - 3 + 20
<u>Simplify by multiplication</u>
f(3) = -45 - 3 + 20
<u>Simplify by subtraction and addition</u>
f(3) = -48 + 20
Hope this helps!! :)

The computation shows that the miles that it is from the post office to the library will be 3575 miles.
<h3>How to illustrate the information?</h3>
It was stated that each block is about
275 meters long and the post office is 13
blocks away from the library.
Therefore, the miles that it is from the post office to the library will be:
= 275 × 13
= 3575 miles.
Therefore, the computation shows that the miles that it is from the post office to the library will be 3575 miles.
