(iii) In the third figure, the graph intersects x-axis
at three points.
Therefore, the number of zeroes of is 3.
(iv) In the fourth figure, the graph intersects x-axis
at two points.
Therefore, the number of zeroes of is 2.
(v) In the fifth figure, the graph intersects x-axis at
four points.
Therefore, the number of zeroes of is 4.
(vi) In the sixth figure, the graph intersects x-axis
at three points.
Therefore, the number of zeroes of is 3.
