Ex. 1:

Quadratic functions can be written in three different forms: general form/standard form, vertex form and factored form. The graph of a quadratic function is always a <a href='[[glossary.html|{"keyword":"Parabola"}]]'>parabola</a>. In this lesson, we will learn how to draw the graph and to find the <a href="[[glossary.html|{"keyword":"x-intercept"}]]">x-intercepts</a>, <a href="[[glossary.html|{"keyword":"y-intercept"}]]">y-intercepts</a>, vertex of quadratic functions in general form.
