Question

Hey can you please help me posted picture of question

Answer 1

Yes he’s right it’s positive infinity so it’s C

Answer 2

The discriminant can be determined from the number of roots of the graph.

If Disc> 0, the function has two distinct roots
If Disc = 0, the function has a repeated root
If Disc < 0, the function has no real root.

Since, the given function has two distinct roots i.e. it cross x-axes at two different points, its discriminant will be positive.

So, the answer to this question is option C<span />
