5.2: Quadratic functions and graphs

1) Lesson Objectives:

You should be able to

• draw quadratic graph

• solve problems on quadratic graphs

Always look through all examples in textbook before lesson.

Drawing of both x and y axes given any scale

Drawing of Quadratic Graphs

Using Quadratic Graph to solve questions

2) Classwork:

TO DO:

You must complete the axes drawing on graph paper before lesson on 5.2.

The axes will be used to draw quadratic graphs from unit 5.2.

Follow closely the video on how to draw axes on a graph paper in the Math website.

Draw the axes for the following graphs.

Note one graph paper for one question.

Total you must have 4 graph papers ready for 4 Feb Lesson.
