IGCSE/O level Additional Mathematics Intro : Mapping

These flashcards show the topic mapping, the basic block of Additional Mathematics

This is a mapping diagram

The rule connecting the input and output values can be written algebraically as: x ↦ x + 2

The mapping can be represented graphically by

plotting values of x + 2 against x

one-one mapping

For 1 input value, there is one output value

many-one mapping

for multiple input values there is one output value

one-many mapping

for one input value there are multiple output values
