Using the Discriminant to Determine the Number of Solutions of Four Quadratic Equations

Relationship Between the Discriminant and the x-Intercepts of a Parabola

In financial forecasting, a quadratic equation can be used to model the points where a company's revenue equals its costs (break-even points). Match the calculated value of the discriminant (b^2 - 4ac) to the number of real-world break-even points it indicates for the business.

A market analyst is using a quadratic equation to determine the equilibrium points for a new product's supply and demand. If the analyst calculates that the discriminant ($b^2 - 4ac$) of the equation is exactly zero, how many real-world equilibrium solutions does the model predict?

In a project cost estimation model represented by a quadratic equation, if the calculated discriminant ($b^2 - 4ac$) is negative (less than zero), the number of real solutions to the equation is ____.

In a business optimization model represented by a quadratic equation, if the discriminant (b^2 - 4ac) is calculated to be exactly zero, the model indicates that there are two distinct real-world solutions.

A data analyst is evaluating the feasibility of three different business growth models using quadratic equations. Arrange the following results of the discriminant ($b^2 - 4ac$) in order based on the number of real solutions they provide, from the fewest solutions (top) to the most solutions (bottom).
