Question

find the shape of graph of equation ax^2+bx+c=0 if a=-2​

Answer 1

Step-by-step explanation:

The graph of y=ax2+bx+c opens upwards when the coefficient of the highest degree term (i.e. x2) is greater than zero.

⇒ a>0.

Answer 2

Answer:

The parabola opens downward.

Step-by-step explanation:

Here, ax²+bx+c=0 and a= -2<0

If a < 0 (negative) then the parabola opens downward.
