Learn what parabolas are and about their main features: their general shape, vertex, and axis of symmetry.

The factored form of a quadratic function is an expression that is, well, factored! Like f(x)=(2x+1)(x-3). Learn how to analyze functions given in this form to find their zeros, their vertex, and their graph.

The vertex form of a quadratic function shows the coordinates of the parabola's vertex. For example, the vertex of g(x)=(x-1)²+2 is at (1,2). Learn how to analyze functions given in this form to find their zeros, their vertex, and their graph.
