Let `f(X) = ax^(2) + bx + c `. Consider the following diagram
.

A

` c lt 0 `

B

`b gt 0 `

C

`a + b - c gt 0`

D

`abc lt 0 `

Text Solution

Verified by Experts

The correct Answer is:
1,2,3,4
Let ` f(x) = ax ^(2) + bx + c `

For the diagram, we can see that ` a gt 0, c lt 0 and - [ b (2a)] lt 0 ` .
Hence , `b gt 0 `
` therefore a + b - c gt 0 `
