From the given figure,find the number of zeros of $y=p(x)$.

(2) The number of zeros of a polynomial $y=p(x)$ is equal to the number of points where its graph intersects the $X$-axis.
In the given figure,the curve $y=p(x)$ intersects the $X$-axis at two distinct points (the origin $O$ and one point on the positive $X$-axis).
Therefore,the number of real zeros of $p(x)$ is $2$.
