Exploring Absolute Value Equations in Algebra

The video tutorial covers the concept of absolute values, explaining them as the distance from zero and always resulting in a positive number. It demonstrates solving equations with absolute values, showing how to interpret them as distances and solve systematically. The tutorial also explores graphing absolute value functions, illustrating how they form a v-shaped graph and discussing scenarios where the function inside the absolute value is positive or negative.

What does the absolute value of a number represent?

• The number squared

• The negative version of the number

• The positive version of the number

• The number divided by 2
