Lesson 6.1: Absolute Values and Absolute Value Functions
Completion requirements
The distance form Lloydminster to High Prairie is about \(600\) km. Does this mean that the distance from High Prairie to Lloydminster is \(–600\) km?
Sometimes the size of a number is more important than its sign. For example, a negative sign is not required to convey the distance between two cities. When only the size of a number is required, an absolute value can be used.
In Lesson 6.1, you will
Sometimes the size of a number is more important than its sign. For example, a negative sign is not required to convey the distance between two cities. When only the size of a number is required, an absolute value can be used.
In Lesson 6.1, you will
- relate absolute values to distances on a number line,
- evaluate expressions containing absolute values,
- graph absolute value functions, and
- interpret absolute value functions.
