Question

If the graph of the quadratic polynomial $f\left(x\right)=a{x}^2+bx+c$ is


Then, the possible value(s) of $a$ can be

• A. $3$
• B. $-5$
• C. $0$
• D. $-2$

Answer 1

Answer: (B), (D)

$-2$

Quadratic polynomial is $f\left(x\right)=a{x}^2+bx+c$


Since, it is a downward parabola, so $a<0$
