What is the axis of symmetry in a quadratic function?

The axis of symmetry of a quadratic function $$y = ax^2 + bx + c$$ is the vertical line given by $$x = -\frac{b}{2a}$$ .

How do you determine if a quadratic opens upwards or downwards?

A quadratic function opens upwards if the coefficient $$a$$ is positive and downwards if $$a$$ is negative.

What is a function's range?

The range of a function is the set of all possible output values (y-values) that the function can produce.

What is a function's domain?

The domain of a function is the set of all possible input values (x-values) that the function can accept.

What is the significance of the discriminant in a quadratic equation?

The discriminant, given by $$D = b^2 - 4ac$$ , determines the nature of the roots of the quadratic equation: if D > 0, there are two real solutions; if D = 0, there is one real solution; if D

What is a quadratic formula?

The quadratic formula is $$x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}$$ , used to find the roots of a quadratic equation.

What does it mean for a function to be increasing or decreasing?

A function is increasing on an interval if the output values rise as the input values increase, and decreasing if the output values fall as the input values increase.
