Answer: $\Large\boxed{f(-9)=-189}$

Step-by-step explanation:

f(x) = -3x² - 6x

<u>Requirements of the question</u>

Find the value of f(-9)

<u>Substitute values into the given function</u>

f(x) = -3x² - 6x

f(9) = -3 (-9)² - 6 (-9)

<u>Simplify the exponent</u>

f(9) = -3 (81) - 6 (-9)

<u>Simplify by multiplication</u>

f(-9) = (-243) - (-54)

<u>Simplify by subtraction</u>

$\Large\boxed{f(-9)=-189}$

Hope this helps!! :)
