Purpose
People credited with this unit standard are able to sketch
graphs of relations and describe features of graphs. This unit
standard is based on objectives from Level 7 of Mathematics in
the New Zealand Curriculum and Tauaki Marautanga
Pangarau.
Classification
Mathematics > Algebra
Available grade
Achieved
Entry information
Recommended skills
and knowledge
Open, but competence is assumed in a number of Level 1
mathematics unit standards, including Unit 5238, Draw and
describe graphs involving two variables.

Learning Programme
This unit standard can be used to assess outcomes of a learning programme based
on achievement objectives from Mathematics in the New Zealand Curriculum
(Learning Media, Ministry of Education, 1992):
Algebra (Exploring patterns and relationships), Level 7, page 158
model a variety of situations, using graphs;
sketch graphs and investigate the graph of a function, using a calculator and
plotting points if necessary;
use graphical methods to investigate a pattern in data and, where appropriate,
identify its algebraic form;
find by inspection, and interpret, maxima, minima, points of inflection,
asymptotes and discontinuities for given graphs;
describe the relationship between members of families of curves in terms of
transformations;
or on Tauaki Marautanga Pangarau (Learning Media, Ministry of Education, 1994),
Taurangi, Taumata 7.
The skills of this unit standard are some of those that could satisfy requirements for
Unit 5243, Apply mathematical processes and skills in problems.

Assessment Notes
The standard must be met with relations from at least four of the following list of
types: quadratic; cubic; circle; rectangular hyperbola; exponential; logarithmic;
trigonometric.
For outcome 2, at least four from the following list of features must be identified:
symmetry; maxima and/or minima; types of discontinuities; asymptotes; behaviour
for large values; transformations of the graph; periodicity.
Calculators, graphics calculators and computers can be used in achievement of
credit for this unit standard.

Sketch graphs of relations.
Evidence requirements
1.1
Sketch is consistent with the information.
Outcome 2
Describe features of graphs.
Evidence requirements
2.1
The description of the features is consistent with the graph.

This CMR can be accessed at http://www.nzqa.govt.nz/framework/search/index.do.
Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMR). The
CMR also includes useful information about special requirements for organisations wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
