Answer: Well to find f(-4) for the function f(x) = x³ - 2x² - x, we substitute -4 for x in the equation and evaluate it.
Replacing x with -4, we get:
f(-4) = (-4)³ - 2(-4)² - (-4)
Simplifying the expression:
f(-4) = -64 - 2(16) + 4
Calculating further:
f(-4) = -64 - 32 + 4
f(-4) = -96 + 4
f(-4) = -92
Therefore, f(-4) equals -92.
