Answer:
y=7
Step-by-step explanation:
x = -1 x is one , replace x with negative one in the equation. using the order of operation PEMDAS.
Remember this -1³= -1×-1×-1=-1
-1²=-1×-1=1.
y =8x³+12x²-6x-3
y= 8(-1)³+12(-1)²-6(-1)-3
<h3>Exponents</h3>
y= 8(-1)+12(1)-6(-1)-3
<h3>Multiplication</h3>
y= -8+12+6-3
<h3>Addition</h3>
y= 10-3
<h3>Subtraction</h3>
y= 7
<h3>Therefore y= 7</h3>
