    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:
    In the standard form of quadratic polynomial, \[a{{x}^{2}}+bx+c,\] a, b and c:

    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.
