Answer 1

Answer:

The vertex of the quadratic curve y=ax

2

+bx+c lies in the fourth quadrant, if

Step-by-step explanation:

For x taking real values, vertex of the parabola lies in fourth quadrant if a<0, i.e, parobola should be downward parabola

See the above diagram for better understanding

In fourth quadrant x>0 and y<0

⇒

2a

−b

>0

As a<0 → b>0
