Have you ever watched a magic show? There are times in a magic show that the magicians use an object such as box, table, hat or cloth to transform an object to become another object, a person with blue cloth to different type and colour of clothes.
from a bird
to become a rabbit
The object that the magicians use to transform an object/ a person to another thing works the same function as function in algebra.
Function (in algebra) works as a machine which can change a 'thing' to become another 'thing'. In the function, there is a rule that enable the function to operate.
Example follows:
Input - Function - Output
The concept claims that it is always one output for every input. Two inputs can give the same output but one input cannot have two different outputs.
