Functions

Select 2 statements that describes the function.

• The domain of the function is { 6,18,30,32}

• The range values are { 3,9,15,16}

• The equation; y = 2x can also represent the table values.

• The range values are { 6,18,30,32}

• The graph of this line will show a decreasing pattern.

• 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}

Identify the DOMAIN of the following relation:

• {-6, 14, 2, 28}

• {(-6,14), (0,32), (2,38), (4,44)}

Is this a function?

• Function

• Not a Function

Which set of values is NOT a function?

• (9,5) (12,5) (15,-5) (17,-5)

• (3,4) (4,-3) (7,4) (8, 8)

• (6,-5) (7, -3) (8, -1) (6, 1)

• (2, -2) (5, 9) (6, -7) (1, 4)

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.
