Question

Find the value of $y=x^3+2$ , when x = -1

• A. 9
• B. 6
• C. 2
• D. 1

Answer 1

The correct option is D

1

$y=x^3+2$

x = -1

$y=(-1{)}^3+2$ $(-1{)}^{oddnumber}=-1$

$y=-1+2$

For any two positive numbers, adding the second to the negative of the first means, subtracting the first from the second

$y=1$
