Question 3
Is this mapping a function?YES or NO
Remember:The “X”s are all different if it is a function
HINT: The points in the mapping are …
(8,7) , (12,0) , (12,3) , (15,7)

Question 4
Does the set of ordered pairs represent a function?
Yes or No(1,8) , (2,11) , (3,14) , (4,17) , (5,20)
Remember:The “X”s are all different if it is a function

Question 7
What are the domain, range, and inverse of the mapping below?
Remember:Domain – all the XsRange – all the YsInverse – the points listed as (y,x)
HINT: The points in the mapping are …
(3,4) , (6,4) , (10,2)

Question 8
Find the domain, range, inverse of the function below:
(5,10) , (6,12) , (7,14) , (8,16) , (10,18)Remember:Domain – all the XsRange – all the YsInverse – the points listed as (y,x)

Question 9
F(x) = x – 4
1. What is the output if the input is 13?2. What is the range if the domain is 20?
Remember:Domain – the inputRange – the output

Question 10
Multiple Choice: Which function increases the input by 8?
A. F(x) = x – 8B. F(x) = x + 8C. F(x) = 8xD. F(x) = x / 8
