There is only one question in Exercise 2.1, the solution for this question is given below.

**Solution:**

Graphical method to find zeroes:-

Total number of zeroes in any polynomial equation = total number of times the curve intersects x-axis.

(i) In the given graph, **the number of zeroes of p(x) is 0 **because the graph is parallel to x-axis does not cut it a any point.

(ii) In the given graph, **the number of zeroes of p(x) is 1** because the graph intersects the x-axis at only one point.

(iii) In the given graph, **the number of zeroes of p(x) is 3** because the graph intersects the x-axis at any three points.

(iv) In the given graph, **the number of zeroes of p(x) is 2** because the graph intersects the x-axis at two points.

(v) In the given graph, **the number of zeroes of p(x) is 4** because the graph intersects the x-axis at four points.

(vi) In the given graph, **the number of zeroes of p(x) is 3** because the graph intersects the x-axis at three points.
