The zeros of a function, f(x), are the values of x for which f(x) = 0.

In the graph, this means that the zeros are the x values for when the graph intercepts the x-axis.

In the given graph, we can see that this happens in two points:

We can see that the second point is exactly at x = 2, so this is one of the zeros. The other is between the 0 and the 1, before the middle, so it is actually between 0 and 1/2.

From the options, we can see that two of them have x = 2 as zero, but one of them has -2 and 2, which is not the case.

The other has 1/4 and 2, which is consistent with the position between 0 and 1/2.

So, the zeros are 1/4 and 2.
