The the output value of f(8) in the given function { f(x) = -3x² - 6x + 1 } is -239.
<h3>What is the output value of f(8) in the given function?</h3>
Given the function in the question;
- f(x) = -3x² - 6x + 1
- f(8) = ?
To determine the output value of f(8), we replace all occurrences of x with 8 in the function and simplify.
f(x) = -3x² - 6x + 1
f(8) = -3(8)² - 6(8) + 1
f(8) = -3(64) - 6(8) + 1
f(8) = -192 - 48 + 1
f(8) = -192 - 48 + 1
f(8) = -240 + 1
f(8) = -239
Therefore, the the output value of f(8) in the given function { f(x) = -3x² - 6x + 1 } is -239.
