Question

Say true or false:

$-3$ is a zero of $y^2+y-6.$

• A. True
• B. False

Answer 1

The correct option is A True

Let $f\left(y\right)=y^2+y-6$.
We know, if $-3$ is zero of $f\left(y\right)$,
then $f(-3)$ must be $0$.
Thus,
$f(-3)=y^2+y-6$
$=-3^2+(-3)-6$
$=0$.

Therefore, the statement is true.

Hence, option $A$ is correct.
