Linear Functions Domain Range

What is the Range of this Function?

• 0 ≤ y ≤ 10

• 193 ≤ x ≤ 250

• 0 ≤ x ≤ 10

• 193 ≤ y ≤ 250

Answer explanation

Range is for the values of y! Do not get tricked! :(

Function f is graphed to the right. What is the range of f?

• -2 ≤ x < 4

• -2 < x ≤ 4

• -3 ≤ y < 3

• -3 < y ≤ 3

What is the domain of this function below?

• x ≤ 3

• y ≤ 3

• x ≥ 2

• y ≥ 2

Joe had a summer job that pays $7.00 an hour and he worked between 15 and 25 hours every week. His weekly salary can be modeled by the equation: y = 7x, where y is his weekly salary and x is the number of hours he worked in a week. What is a reasonable range for this function?

• {15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25}

• {105, 112, 119, 126, 133, 140, 147, 154, 161, 168}

• {y | 15 ≤ y ≤ 25}

• {y | 105 ≤ y ≤ 168}

What is the range of the following relation?

• R={-2, -1, 4, 5}

• R={1, 2, 4, 5}

• R={-3, 0, 3, 5, 7}

• R={0, 3, 5, 7}

What is the DOMAIN of this graph? 
Remember DOMAIN is "x" values that go left to right. 

• -4 ≤ x ≤ 3

• -1 ≤ x ≤ 4

• 4 < x < 3

• -1 < x < 4

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}

What is the range of the graph?
Remember: Range is y! 

• 1 ≤ x ≤ 5

• 1 < x < 5

• 1 ≤ y ≤ 5

• 1 < y < 5

All of the y values or outputs are called what?

• Domain

• Range

What is the domain of the graph?
Remember:   Domain is the "x" values from left to right

• -7 ≤ x < 5

• -3 ≤ x < 1

• -3 ≤ y < 1

• -7 ≤ y < 5
