Identify the interval where the graph of a quadratic function is positive: $$(-3,1)$$ .

The graph is positive in the interval $$(-3,1)$$ .

How do you determine the vertex of a quadratic function in standard form $$y = ax^2 + bx + c$$ ?

The vertex can be found using the formula $$x = -\frac{b}{2a}$$ .

What is the general shape of a quadratic function's graph?

The graph of a quadratic function is a parabola.

What are the x-intercepts of a quadratic function?

The x-intercepts are the points where the graph crosses the x-axis, found by solving $$ax^2 + bx + c = 0$$ .

What is the significance of the leading coefficient (a) in a quadratic function?

If $$a > 0$$ , the parabola opens upwards; if $$a

What is the difference between increasing and decreasing intervals in a quadratic function?

Increasing intervals are where the function's values rise as x increases; decreasing intervals are where the function's values fall.

How can you determine the solutions of a quadratic equation graphically?

By identifying the x-intercepts of the graph.

What is the vertex form of a quadratic function?

The vertex form is $$y = a(x - h)^2 + k$$ , where (h, k) is the vertex.

What is the discriminant of a quadratic equation and what does it indicate?

The discriminant is $$b^2 - 4ac$$ ; it indicates the nature of the roots: two real roots, one real root, or no real roots.

How do you find the range of a quadratic function?

The range can be determined by the vertex and the direction the parabola opens.
