*Cbse Ncert Solutions of Mathematics Textbook Exercise 2.1*

Question 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.
(Source: Class 10 NCERT Math Textbook)

Solution:

(i) The number of zeroes is 0 because the
graph does not intersect x-axis at any point.

(ii) The number of zeroes is 1 because the
graph intersects x-axis at only 1 point.

(iii) The number of zeroes is 3 as the
graph intersects x-axis at 3 points.

(iv) The number of zeroes is 2 as the
graph intersects x-axis at 2 points.

(v) The number of zeroes is 4 as the
graph intersects x-axis at 4 points.

(vi) The number of zeroes is 3 as the
graph cuts x-axis at 3 points.
