| Case Study : Q. 21 to 25 |
| In a classroom, four students Anil, Jay, Richa and Suresh were asked to draw the graph of \[p(x)=a{{x}^{2}}+bx+c\]. |
| Following graphs are drawn by the students: |
 |
| Based on the above graphs, answer the following questions: |
A) 1
B) 2
C) 3
D) 4
Correct Answer: B
Solution :
| For any quadratic polynomial \[a{{x}^{2}}+bx+c,\]the graph of the corresponding equation has one of the two shapes either open upwards like \[\cup \]or open downwards like \[\cap .\] Hence, Anil and Suresh have drawn the correct graph. |
| So, option [b] is correct. |
