ANSWER

1. No real roots

2.

3. The discriminant is negative.

EXPLANATION

1. The given equation is

We have a=-2,b=-9 and c=-5.

The discriminant is given by:

This simplifies to:

Since the discriminant is less than zero, the quadratic equation has no real roots.

2. The given equation is:

We have a =-2, b=-7 and c=-2.

The roots of this equation are given by;

We plug in the values to get;

3. The given graph is hanging downwards. This means that it doesn't have x-intercepts.

Therefore the roots are complex or imaginary.

This implies that, the discriminant of the corresponding equation is negative.
