Look at the graph given below. It is the graph of $y = p(x)$ where $p(x)$ is a polynomial. Find the number of zeroes of $p(x)$.

(1) The number of zeroes of a polynomial $p(x)$ is equal to the number of points where the graph of $y = p(x)$ intersects the $X$-axis.
In the given graph,the line intersects the $X$-axis at exactly $1$ point.
Therefore,the number of zeroes of $p(x)$ is $1$.
