Question

If the diagram in figure shows the graph of the polynomial $f\left(x\right)=a{x}^2+bx+c,$ then

• A. $a>0,b<0$ and $c>0$
• B. $a<0,b>0$ and $c<0$
• C. $a<0,b>0$ and $c>0$
• D. $a<0,b<0$ and $c<0$

Answer 1

The correct option is A $a>0,b<0$ and $c>0$


Curve $a{x}^2+bx+c$ intersects x-axis at two points and curve is upward.
$a>0,b<0$ and $c>0$
