Answer :
Answer:
-28
Step-by-step explanation:
To find f(3), we substitute x = 3 into the function:
f(x) = -5x² - x + 20
f(3) = -5(3)² - (3) + 20
f(3) = -5(9) - 3 + 20
f(3) = -45 - 3 + 20
f(3) = -48 + 20
f(3) = -28
Therefore, f(3) = -28.

Step-by-step explanation:
To find f(3), we substitute x = 3 into the function:

f(3) = -48 + 20
f(3) = -28
Therefore, f(3) = -28.
