Domain Range Points

The set of all the outputs of a relation are called _____.

• domain

• range

What is the domain?

• {-6, 14, 2, 28}

• {(-6,14), (0,32), (2,38), (4,44)}

• {-6, 0, 2, 4}

• {14, 32, 38, 44}

What is the range?

• <-7, 5, -2, -4>

• <-2, 5, 7>

• <-4, 3, 6>

• <-3, -6,-4>

Is the relation shown a function?

• No, because the x-value 11 is paired with 5 and 8.

• Yes, because each x-value has only one y-value paired with it.

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

• D:{0, 1, 2, 3, 4}
  R:{1, -3, -4}

What is the range of the following relation?

{(-5, 4), (-4, -1), (-2, 1), (0, 4), (1, 3)}

• R={-5, -4, -2, 0, 1}

• R={0, 1, 2, 4, 5}

• R={-1, 1, 3, 4}

Is this relation a Function?

• Yes

• No

• I Don't Know

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.

What is the range?

• {1, 2, 3, 4, 5, 6}

• {0, 1, 2, 3, 4, 5, 6}

• {2, 4, 8}

• {-1, 0, 1, 2, 3, 6}

Does the graph represent a function?

• Yes

• No
