If x = -1, what is the value of y in the equation?y = 8x3 + 12x2 - 6x - 3

Bezzdna [24]

<h3>Answer: y = 7</h3>

Work Shown:

$y = 8x^3 + 12x^2 - 6x - 3\\\\y = 8(-1)^3 + 12(-1)^2 - 6(-1) - 3\\\\y = 8(-1) + 12(1) - 6(-1) - 3\\\\y = -8 + 12 + 6 - 3\\\\y = 7\\\\$

Explanation:

I replaced every x with -1. Then used the order of operations (PEMDAS) to simplify. Keep in mind that $(-1)^2 = (-1)*(-1) = 1$ and not $(-1)^2 = -1$
