Consider that the zeroes of a function y=f(x) are the values of 'x' for which the function becomes zero.
These zeroes can be obtained by solving the equation,
[tex]f(x)=0[/tex]
Since the values of the function are plotted on the vertical axis, it can be claimed that the zeroes are the x-coordinate of points at which the y-coordinate becomes zero.
Now, observe the graph carefully.
There are two such points at which the y-coordinate becomes zero. These points are -1 and 3.
So, the zeroes of the function are -1 and 3.
