Verify whether the following is True or False:
$-\frac{1}{3}$ is a zero of $3x + 1$.

(A) zero of a polynomial $p(x)$ is a value $c$ such that $p(c) = 0$.
Let $p(x) = 3x + 1$.
To verify,substitute $x = -\frac{1}{3}$ into the polynomial:
$p\left(-\frac{1}{3}\right) = 3\left(-\frac{1}{3}\right) + 1$
$p\left(-\frac{1}{3}\right) = -1 + 1 = 0$.
Since $p\left(-\frac{1}{3}\right) = 0$,it is confirmed that $-\frac{1}{3}$ is a zero of the polynomial $3x + 1$. Therefore,the statement is True.
