NCERT Solutions for class 10 maths chapter 2 Exercise 2.1

1.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

. (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.
