Question

From the below figure which of the following is not the graph of a quadratic polynomial?

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

Explanation for graph of quadratic polynomial

• A quadratic polynomial is a polynomial of degree two i.e. the highest exponent of the variable is $2$. In general, a quadratic polynomial will be of the form: $p\left(x\right)=a{x}^2+bx+c$ where $a\ne 0$.
• The graph of a quadratic polynomial is a parabola with standard form $f\left(x\right)=a{x}^2+bx+c$
• All the above graphs are parabola except the graph in option D.

Hence, the correct option is option D
