Q1 The graphs of y = p(x) are given in Fig. 2.10 below, for some polynomials p(x). Find the number of zeroes of p(x), in each case. Ans: Total no of zeroes of a polynomial equation = the number of times the curve intersect xaxis
 In this graph the number of zeroes of p(x) is 0, because the graph is parallel to x axis and does not intersect at any point on xaxis.
 In this graph the number of zeroes of p(x) is 1, because the curve intersects xaxis only at one point.
 In this graph the number of zeroes of p(x) is 3, because the curve intersects xaxis at three points.
 In this graph the number of zeroes of p(x) is 2, because the curve intersects xaxis at two points.
 In this graph the number of zeroes of p(x) is 4, because the curve intersects xaxis at four points.
 In this graph the number of zeroes of p(x) is 3, because the curve intersects xaxis at three points.
