Solution:

- Graph does not intersect at any point on x-axis, hence there is no zeroes.
- Graph intersect at one point on the x-axis, hence the number of zeroes is 1.
- Graph intersect at three points on the x-axis, hence the number of zeroes is 3.
- Graph intersect at two points on the x-axis, hence the number of zeroes is 2.
- Graph intersect at four points on the x-axis, hence the number of zeroes is 4.
- Graph intersect at three points on the x-axis, hence the number of zeroes is 3.
