We agree to :

K: Know the sequence and relationship of operations relating one set of numbers to another

U: Functions are relationships or rules that associate numbers from one set to another

D: Able to identify the sequence andrelationship of operations relating one set of numbers to another
 set. 

Tell us what you understand about the relationship between 2 sets of number?

RECAP and RECALL: What do you remember about rules of number pattern?

Know the sequence and relationship of operations relating one set of numbers to another

SET 1: 1, 2, 3, 4, 5......

SET 2: 3, 6, 9, 12, 15......

FUNCTION: relationship of a set of inputs to a set of possible outputs where each input is related to exactly one output.

INPUT: The input is the number you feed into the expression, 

OUTPUT: Output is what you get after the look-up work or calculations are finished.

FUNCTION MACHINE: Diagram that represents a machine that takes an input, applies a rule such as a set of operations and delivers the answer as an output.

What is the output if the input is as below:
2,4,6,8,10.....

Function: 2n -2

1. 4, 8, 6, 12, 10
2. 2, 6, 10, 14, 16....
3. 4, 8, 12, 16, 20
4. 2, 8, 16, 32, 64

What is the function of the input and output below?
input (x): 3,4,5,6,7,8
output (y): 4,5,6,7,8

1. x+1
2. y+1
3. x+3-2
4. y+3-2

EXIT TASK/REFLECTION
