Question

For the given graph of a quadratic equation as shown $y=a{x}^2+bx+c,$

• A. $a<0\&D=0$
• B. $a<0\&D<0$
• C. $a<0\&D>0$

Answer 1

The correct option is B $a<0\&D<0$

Given graph of $y=a{x}^2+bx+c$ as shown:

Here, the graph is opening downward $\Rightarrow a<0$
Also, it is not touching intersecting the $x-$ axis at any point.
$\Rightarrow D<0$
