## Polynomials – Exercise 2.1 – Class 10

1. The graphs of y = p(x) are given in following figure, for some polynomials p(x). Find the number of zeroes of p(x), in each case. (i) (ii) (iii) (iv) (v) (vi) Solution: (i) The number of zeroes is 0 as the graph does not cut the x-axis at any point. (ii)The number of zeroes is… Continue reading Polynomials – Exercise 2.1 – Class 10
