Question-1 :-  The graphs of y = p(x) are given in Figures below, for some polynomials p(x). Find the number of zeroes of p(x), in each case.

(i) The number of zeroes is 0 as the graph intersects the x-axis at no any point. 
(ii) The number of zeroes is 1 as the graph intersects the x-axis at one point only. 
(iii) The number of zeroes is 3 as the graph intersects the x-axis at three points. 
(iv) The number of zeroes is 2 as the graph intersects the x-axis at two points.
(v) The number of zeroes is 4 as the graph intersects the x-axis at four points. 
(vi) The number of zeroes is 3 as the graph intersects the x-axis at three points.
