Functions and Their Properties

Functions and Their Properties

The relationship and change of variables is largely explained through understanding functions and their properties. With this subject, students practice looking at the patterns in math, reading graphs and realizing that certain values can determine various outcomes. Whenever functions are utilized, they help in learning algebra, calculus and when applying math to real life.

Domain/Range

They are shown how to determine the domain and range of a function. The ideas play a key role in explaining the rules and boundaries of functions. This concept helps students draw graphs that are accurate and not confusing.

Increasing/Decreasing

Learners pay attention to the intervals where the output of a function is increasing or decreasing. They work with graphs and adopt specific symbols to detail different points in a function. They are essential for analyzing trends and noticing what functions do in the financial or physical world.

Activity Idea

Function Walk - Plot points on graph paper to observe where functions increase or decrease and their domain/range.

Entertainment Activities

1. Graph Drawing โ€“ Draw functions showing increasing and decreasing parts.

2. Real-life Functions โ€“ Chart temperature or growth over time.

3. Domain/Range Hunt โ€“ Identify domain and range in everyday contexts (e.g., time, height).
