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

Evaluate 4x3 + 2 for x = -1
Darina [25.2K]
4 {x}^{3} + 2

Plug in -1 for x

and you'll get this:
4 {( - 1)}^{3} + 2

Solve it further and you'll get:
4( - 1) + 2 \\ = - 4 + 2 \\ = - 2

Therefore,
4 {x}^{3} + 2
where x = -1
