| Case Study - 1 : Q. 1 to 5 |
| The below pictures show few natural examples of parabolic shape which can be represented by a quadratic polynomial. A parabolic arch is an arch in the shape of a parabola. In structures, their curve represents an efficient method of load, and so can be found in bridges and in architecture in a variety of forms. Based on the above information, answer the following questions: |
 |
A) all are real numbers
B) all are rational numbers
C) 'a' is a non-zero real number and b and c are any real numbers
D) all are integers
Correct Answer: C
Solution :
| A polynomial in the form of \[a{{x}^{2}}+bx+c\]where a, b and c are real numbers and \[a\ne 0\]is known as a quadratic polynomial. |
| So. option [c] is correct. |
