Question

When y = x^2, which of the following expressions is
equivalent to –y ?

Answer 1

The expression equivalent to -y when y = x² is -x².

Step-by-step explanation:

To find an expression equivalent to -y when y = x², we can simply negate the value of y. So, -y = -(x²) = -x².

In this case, the expression equivalent to -y is -x².

Answer 2

-y=-(x^2) because you multiply both sides by -1.
