This achievement standard asks you to solve problems using graphs and graphical techniques. You'll work with linear and non-linear functions, understand how their features appear on graphs, and use graphs to find solutions to real-life or mathematical problems.
What you actually do
- ·Select the appropriate graphical method to solve the problem
- ·Draw or interpret graphs accurately, showing knowledge of features like intercepts, shape, and behaviour
- ·Read values and solutions directly from your graphs
- ·Explain how your graph connects to the problem context or the mathematical relationships involved
- ·Use proper mathematical language and notation when describing your work
AAchieved
You solve problems by correctly using graphical methods, showing you understand the features and equations of the graphs involved.
MMerit
You select and apply graphical methods strategically to solve problems, connecting different representations and explaining how your findings relate to the problem situation.
