**Question 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.**

Answer

(i)the graph does not intersect the x axis so that there are no zero in this graph

(ii)the graph intersects the x axis at one places so that here are one zeros in this graph

(iii)the graphÂ intersects the x axis at three places so that there are three zeros in this graph

(iv)the graph intersects the x axis at two places so there are two zeros in this graph

(v) the graph intersect the x axis at four places so there are four zeros in this graph

(vi) the graphÂ intersects the x axis at three places so that there are three zeros in this graph
