Simple Functional Relations is a part of the VCE Maths Methods topic Algebra. It looks at the use of simple functional relations to characterise properties of functions including periodicity and symmetry.
What are Functions and Relations?
This next video introduces functions and relations. A relation is a set of ordered pairs, so anything on a cartesian plane is a relation.
How to Equate Coefficients
The following video explains how to equate coefficients, to find the numbers in front of the x in functions.
Periodic Functions
This next video explains periodic functions. A periodic function is defined as a graph which displays translational symmetry.
This video explains translational symmetry, which will be useful in understanding periodic functions further.
