Unit 2 - Graphs and GDC

Unit Objectives
Prior Knowledge/For Review – Students should be able to:

• Use function notation to map a set of numbers to another set of numbers
• Use linear equations to map a set of numbers to another set of numbers
• Generate coordinate pairs and plot graphs of linear functions
• Generate coordinate pairs and plot graphs of non-linear functions

IGCSE Core Learning Objectives – Students should be able to:

• Be able to use function notation (Video 2.01 First on page)
• Understand the terms domain and range (Video 2.02 Third on page) (Questions 2.02)
• Work with mapping diagrams (Video 2.03 Second on page) (Questions 2.03)
• Use of a GDC to:
  • Sketch the graph of a function (and adjust axes as appropriate)
  • Produce a table of values
  • Find zeros, local maxima or minima (Video 2.05 Second on page) (Questions 2.05) (Video 2.06 Third on page) (Question 2.06)
  • Find the intersection of the graphs of functions
  • Solve equations, including those which may be unfamiliar (Video 2.07)
