Exploring Quadratic Graphs

Topics for Today:

Today we began our work on quadratic functions.  Quadratic functions, simply stated, are functions that have a variable with the highest degree exactly equal to two.  We looked at the standard form of a quadratic function and looked at graphs of different parabolas.

Vocabulary: quadratic function, standard form of a quadratic function, parabola, axis of symmetry, vertex, minimum, maximum

Resources & Tutorials:

1) What is a quadratic function?
2) What is a parabola?

Absolute Value Translations

Topics for Today:

Today we began our discussion of graphing absolute value functions through a DESMOS activity in class.  The purpose of the activity was to allow students to explore the various parts of an absolute value equation and to draw their own conclusions about how changing various pieces of the equation affects how the graph looks.  All of these variations are called translations.

Vocabulary: absolute value graph, translation, vertex
