. (i) the number of zeroes is 0 because the graph is parallel to x-axis does not cut it at any point.

(ii) the number of zeroes is 1 because the graph intersects the x-axis at only one point.

(iii) the number of zeroes is 3 because the graph intersects the x-axis at any three points.

(iv) the number of zeroes is 2 because the graph intersects the x-axis at two points.

(v) the number of zeroes is 4 because the graph intersects the x-axis at four points.

(vi) the number of zeroes is 3 because the graph intersects the x-axis at three points.
