This a learning material (Module). It contains lesson on notions of domain and range, how to sketch graphs of a function, and the characteristics of the graphs of linear functions using the given linear equation. It helps develop skills in stating domain and range in a given function, and applying linear functions to solve problems.
Objective
1. to state the domain and range of a given function
2. to construct the graphs of a function described by a table of ordered pairs, and vice versa
3. to identify the different properties of a function such as the intercepts; slope and the trend (decreasing or increasing) from its graph
4. to define the slope of a line
5. to express a linear equation in slope-intercept form
6. to apply linear functions to solve word problems
