1.
2.
3.
4.
5.
6.

Solution:

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