Graphing Absolute Value Functions in Algebra

This video tutorial covers algebra lesson 5-8 on graphing absolute value functions. It begins with an introduction to absolute value functions, explaining their v-shaped graphs. The lesson then explores graph translations, both horizontal and vertical, and introduces piecewise and step functions. The tutorial includes detailed examples of graphing absolute value equations and explains how to perform horizontal and vertical translations. A practical example of a step function is provided using a scenario involving buses and students. The lesson concludes with a closure question summarizing the key concepts.

What shape does the graph of an absolute value function typically have?

• A circle

• A parabola

• A V-shape

• A straight line

What is a piecewise function?

• A function with a single rule for all values

• A function that only has positive values

• A function with different rules for different parts of its domain

• A function that is always increasing
