Given the function f(x) = -5x²-x+ 20, find f(3).<br> O-28<br> O-13<br> O62<br> O64

olganol [36]

Answer: $\Large\boxed{First~Choice.~-28}$

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

$\Large\boxed{f(3)=-28}$

Hope this helps!! :)
