Question

Statement I: In the given figure , we must have a>0,4>() and y = ax? + bx + c >0 a > 0 > X - axis Statement II: In the given figure, we must have a0 and y = ar? +bx+c​

Answer 1

Answer:

Since parabola is upward a>0

Curve is crossing x-axis at two points ⇒ roots are real ⇒b

2

−4ac>0

Roots are of opposite signs c/a<0⇒c<0

Also magnitude of +ve root is larger ⇒ sum of roots >0

⇒−b/a>0⇒b<0

Hence all the options are correct
