## Subject Wise NCERT Exemplar Solutions

1. What is the graph representation of polynomials according to NCERT syllabusClass 10 Maths?

Graph representation of a polynomial is plotting the values of x against the evaluated values of y and then analyzing the characteristics of the graphs whether it has no solution, one solution, two solutions or infinite solution etc depending upon how many times the graph intersects the x-axis.

2. What is meant by the zero of the polynomial?

The value of x for which the polynomial becomes zero.

3. How are the graphs plotted?

Consider y=P(x) be any polynomial equation. To plot in the graph evaluate the value of y for each value of x and find ordered pair such as (considered value of x , evaluated value of y) plot it in the graph against the cartesian plane(a cartesian plane is a plane consisting of x-axis and y-axis).

4. Which graph represents the polynomial with infinite zeros?

The graph in which there is a straight line coincident with the x-axis, it represents the graph with infinite solutions.

5. Which graph represents the polynomial with no solution?

Any graph which does not intersect the x-axis represents the graph with no solution.

6. Is the degree of the polynomial always equal to the number of zeroes?

No, it is not necessary.

For eg: A quadratic graph that does not intersect the x-axis has degree 2 but has 0 zeroes.

hello Zaid,

Yes, you can apply for 12th grade as a private candidate .You will need to follow the registration process and fulfill the eligibility criteria set by CBSE for private candidates.If you haven't given the 11th grade exam ,you would be able to appear for the 12th exam directly without having passed 11th grade. you will need to give certain tests in the school you are getting addmission to prove your eligibilty.

best of luck!
