Graphing a quadratic function in standard form

The video tutorial explains how to graph quadratic equations in the form y = ax^2 + c. It covers the changes in vertex and axis of symmetry, the process of creating a table of values, and calculating coordinates. The tutorial also demonstrates plotting points to form a parabola and discusses the significance of the vertex, axis of symmetry, and intercepts.

What are the steps to evaluate the Y coordinate for given X coordinates in the quadratic equation?

How does the value of 'a' affect the direction in which the parabola opens?

What is the significance of the Y intercept in relation to the vertex of the quadratic equation?
