Question

For which discriminant is the graph possible?


b2 – 4ac = 0

b2 – 4ac = –2

b2 – 4ac = 6

Answer 1

Hey user☺☺

Option a is correct

Because the graph has only one solution.

As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution amd therefore the discriminant will be 0.

Hope this will help☺☺

Answer 2

The parabolic graph is possible for b^2 – 4ac = 0.

What is a parabola?

Parabola, open curve, a conic phase produced by the intersection of a proper round cone and an aircraft parallel to the detail of the cone.

• A parabola is a U-fashioned curve this is drawn for a quadratic characteristic, f(x) = ax2 + b x + c.
• The graph of the parabola is downward (or opens down), while the value of a is less than 0, a < 0.
• The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > zero.
• A parabola is not anything but a U-shaped plane curve.
• Any point on the parabola is equidistant from a fixed factor known as the focus and a fixed straight line known as the directrix. terms related to Parabola.
