Solution

The correct option is D
The equation is always considered a second degree equation.

General form of a quadratic equation is $a x^{2} + b x + c = 0$

If a is negative,the graph is decreasing.

If the roots are not real, then it will not intersect x – axis

If c is not equal to 0, then it will not be symmetric about the y-axis

But, the equation is always considered a second degree equation.
