It is positive true of the discriminant for the graph below.
What is the discriminant for the graph?
The discriminant is the expression b² - 4ac for the quadratic equation ax² + bx + c = 0. The discriminant's value reveals how many roots f(x) has: - The quadratic function has two unique real roots if b² - 4ac > 0, otherwise it does not. The quadratic function has one repeating real root if b² - 4ac = 0.
The discriminant informs you of the number of quadratic equation solutions or x-intercepts for a parabola.
The values for x that cause the equation to equal 0 are known as the roots, zeros, or solutions. This is when the parabola crosses the x-axis on a graph. The graph will twice cross the x-axis whenever the discriminant is positive.
Given
In the graph, the parabola crosses x- the axis at (0,4) and (2,0)
