Which of the following is a function? Why?
A.{(1, 4), (2, 5), (3, 6), (4, 8)}
B.{(2, 1), (3, 1), (3, 3), (2,2)}
A , Because each domain has its own range.

Does the graph represent a function? Why?
Yes, because it passes the vertical line test.
200

200
Find the DOMAIN:
{(-2, 4), (3, 2), (2, 10)}
What is {-2, 2, 3}?
200
The vertical axis of the coordinate plane is called the____?
y axis
300
This word describes a relation that pairs each x value with only one y value.
Function
300
Is this a function and why?
Does the graph represent a function?
No, because x's repeat at 8.
300
Based on the graph of the function, what is f(4)?
f(4) = -2
300
What is the domain of the function 
What is {-3,-1,2, 4}
300
A set of ordered pairs is called a____?
Relation

Vertical Line Test
400
Does the following table represent a function?
x y
1 2
2 5
6 2
2 9
5 1
No, because the input (x) of 2 has two different outputs (y)

This is a function in which f(x) = mx + b, where m and b are real numbers, and m and f(x) are not both equal to zero.
Linear Function
500
Does the graph represent a function? Why?
No, because it fails the vertical line test.
