CCSS.HSF.IF.A.1

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain.
Remember:  Domain is x 
(x,y)

• D: {1, -3, -4,}
  R: {0, 1, 2, -4}
• D:{0, 1, 2, -4}
  R:{1, -3, -4}
• D:{0, 1, 2, 3, 4}
  R:{1, -3, -4}

Identify the domain of the following relation:
Remember domain is the "x" values

• -6, 14, 2, 28
• (-6,14), (0,32), (2,38), (4,44)
• -6, 0, 2, 4
• 14, 32, 38, 44

CCSS.HSF.IF.A.1

What is the range of the following relation:
(9, -2) (4, 3)  ( 8, 10) ( -4, 8)
Range is the y values 
(x,y)

• -4, 4, 8, 9
• -2, 3, 8, 10
• (9, -2) ( 4, 3)
• (8, 10) (-4, 8)

What is the DOMAIN of this graph? 
Remember DOMAIN is "x" values that go left to right. The answer is written as (smallest number) $\le$  x $\le$  (biggest number)

• -4 ≤ x ≤ 3

• -1 ≤ x ≤ 4

• 4 < x < 3

• -1 < x < 4

What is the range of the graph?

Remember: Range is y!

The answer is written as (smallest number) ≤ y ≤ (biggest number)

• 1 ≤ x ≤ 5

• 1 < x < 5

• 1 ≤ y ≤ 5

• 1 < y < 5

What is the domain of the graph?

Remember: Domain is x.

The answer is written as (smallest number) ≤

x ≤ (biggest number)

• 1≤ x ≤ 4

• 1 < x < 4

• 1≤ y ≤ 4

• 1 < y < 4

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 range?
Remember range is the "y" values (up and down) 
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
