What is the formula to find the maximum height of a projectile?

The maximum height is given by $$h_{max} = -\frac{D}{4A} + C$$ , where D is the linear coefficient, A is the quadratic coefficient, and C is the constant term.

What is the significance of the 'a' value in a quadratic function?

The 'a' value determines the direction of the parabola (upward or downward) and affects the width of the graph.

What is the quadratic formula?

The quadratic formula is used to find the roots of a quadratic equation and is given by $$x = \frac{-b \text{±} \text{√}(b^2 - 4ac)}{2a}$$ .

What is the discriminant in a quadratic equation?

The discriminant is the part of the quadratic formula under the square root, $$b^2 - 4ac$$ , which determines the nature of the roots.

What does a positive discriminant indicate?

A positive discriminant indicates that the quadratic equation has two distinct real roots.

What does a zero discriminant indicate?

A zero discriminant indicates that the quadratic equation has exactly one real root (a repeated root).

What does a negative discriminant indicate?

A negative discriminant indicates that the quadratic equation has no real roots (the roots are complex).

How can you determine the y-intercept of a quadratic function?

The y-intercept can be found by evaluating the function at $$x = 0$$ , which gives $$y = c$$ in the standard form $$y = ax^2 + bx + c$$ .

What is the relationship between the vertex and the axis of symmetry?

The vertex lies on the axis of symmetry, which divides the parabola into two mirror-image halves.
