FOR ONLINE READING ONLY
1. Assist students through group discussion to perform Activity 4.1
in the Student’s Book on identifying a function from the drawn
graph. Advise students to write their findings on a flip chart
or manila card ready for presentations or gallery walk. Assist
students through discussion to recognize the general form of a
polynomial function

y = f ( )x = a x + a x n− 1 ++ 2 2 ax a+ 0 ,where n∈ . 
... a x +

2. Assist students through group discussion to classify polynomial
functions according to their degree.
3. Use Figure 4.1 in the Student’s Book to assist students in
drawing the graph of ( )f x = mx + , c m > 0.

4. Use Examples 4.1 and 4.2 in the Student’s Book to assist students
through discussions to sketch graphs of linear equations. Engage
students to use GeoGebra or any other mathematical software

to verify the answer to a given example.
5. Instruct students to attempt Exercise 4.1 in the Student’s Book.

Advise them to submit their work, check the correctness of
the answers, and provide them constructive feedback where
necessary.
