Which of the following represents a function?

• {(1,2), (1,3), (1,4), (1,5)}

• {(1,2), (2,3), (3,4), (4,5)}

• {(1,2), (3,4), (3,5), (6,7)}

• {(1,2), (3,4), (5,6), (5,8)}

What is the domain of the graph?
Remember:  Domain is x

• 1≤ x ≤ 4
• 1 < x < 4
• 1≤ y ≤ 4
• 1 < y < 4

Which graph does NOT pass the vertical line test?

• Graph 1
• Graph 2
• Graph 3
• Graph 4

What is the range of the graph?
Remember: Range is the "y" values (up and down) 

• -7 ≤ x < 5
• -3 ≤ x < 1
• -3 ≤ y < 1
• -7 ≤ y < 5

What is the domain?
Remember domain is the "x" values. 
And an open circle means it DOES NOT equal that number - use < and >
Only use ≤ and ≥ with a closed circle.

• -4 < x ≤ 5
• -4 ≤ x < 5
• -3 < y < 3
• -3 ≤ y ≤ 3

What is the DOMAIN of this graph? 
Remember:  DOMAIN is the x from left to right. 

• x < -3
• x ≤ -3
• x > -3
• x ≥ -3
