To determine which circles have their centers on the x-axis, you need to look at the equation of the circle. The general equation of a circle is (x-h)² + (y-k)² = r², where (h,k) is the center of the circle and r is the radius.

If a circle has its center on the x-axis, then the y-coordinate of the center (k) must be 0. Therefore, you need to look for circles where the y-coordinate of the center is 0.

For example, the circle with equation (x-3)² + (y-0)² = 4 has its center on the x-axis because the y-coordinate of the center is 0.

On the other hand, the circle with equation (x-1)² + (y-2)² = 9 does not have its center on the x-axis because the y-coordinate of the center is 2, not 0.

So, to answer your question, you need to look at the equations of the circles and determine whether the y-coordinate of the center is 0.
