What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of a parabola, depending on its orientation.

What is a quadratic equation?

Back

A quadratic equation is a polynomial equation of the form ax² + bx + c = 0, where a, b, and c are constants.

Front

What does the term 'y-intercept' mean?

Back

The y-intercept is the point where the graph crosses the y-axis, represented as (0, y).

How can you identify the vertex from a quadratic equation in standard form?

Back

The vertex can be found using the formula (-b/2a, f(-b/2a)).
