Linear Equations

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 table?

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

CCSS.HSF.IF.A.1

State the range of the relation. 
{ (3, -2) , (4, -3), (5, -4), (6, 0) }

• (3, -2, 4, -3)
• (-2, -3, -4, 0)
• { -2, -3, -4, 0 }
• { 3, 4, 5, 6 }

CCSS.8.F.A.1

State the domain of the relation. Write it in set notation.
{(8, 5), (-6,-9), (2, 5), (0, -8)}

• {(8, 5), (-6,-9), (2, 5), (0, -8)}
• {-6, 0, 2, 8}
• {-9, -8, 5}
• 8 -6 2 0

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.

Is this table a function or not a function?

• Function

• Not a Function

For the function f(x) = -3x + 3 find f(0).

• 0

• -3

• 3

• -1

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values
• No, because the vertical line test shows there are repeating input values
