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>
