Domain and Range of Discrete Graphs

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

All of the y values or outputs are called what?

• Domain

• Range

All of the x values or inputs are called what?

• Domain

• Range

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)

Is the following graph continuous or discrete? What is the domain and range?

• Discrete

  D: {1, 2, 3, 4, 5, 6}

  R: {-1, 0, 1, 2, 3, 6}

• Discrete

  D: {-1, 0, 1, 2, 3, 6}

  R: {1, 2, 3, 4, 5, 6}

Is the following graph continuous or discrete? What is the domain and range?

• Discrete

  D: {-5, -3, 1, 2, 4}

  R:{ -5, -3, 1, 2, 5}

• Discrete

  D:{ -5, -3, 1, 2, 5}

  R: {-5, -3, 1, 2, 4}

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D: {1, -3, -4,}
  R: {0, 1, 2, -4}

• D: {-4, 0, 1, 2}
  R:{-4, -3, 1}

• D: {0, 1, 2, 3, 4}
  R:{1, -3, -4}

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

What is the domain?

• all real numbers

• 1<x<6

• {1,3,4,6}

• {-2,2,5}

Find the DOMAIN

• {-5, -2, 1, 4}

• {1, -2, 4, -5}

• x ≥ 1

• 1 ≤ x ≤ 5

• 1 ≤ x ≤ 4

• x ≤ 5

• All real numbers
