This video tutorial covers graphing quadratic functions in intercept form. It explains the intercept form, identifies x-intercepts, and describes the axis of symmetry. The video details how the graph's behavior changes based on the value of 'a', including vertical stretch and shrink. It provides a step-by-step guide to graphing, including identifying x-intercepts, drawing the axis of symmetry, finding the vertex, and drawing a smooth curve. An example problem is solved, and viewers are encouraged to practice. The video also covers converting between intercept and standard forms.

What does 'P' represent in the intercept form of a quadratic function?
