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
