Function Relations and Linear Graphis -PreALgebra

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

Which graph is NOT a function? (It does NOT pass the vertical line test.)

• Graph 1

• Graph 2

• Graph 3

• Graph 4

Is this graph a function or not a function? 

• Function 
• Not a Function 

In the given relation, what domain value corresponds to the range value -2?
{(-1,2), (-2,4), (2,5), (0,-2), (2,0)}

• -2
• 0
• 2
• 4

Which set of values is a function?

• (9,5) (10,5) (9,-5) (10,-5)
• (3,4) (4,-3) (7,4) (3, 8)
• (6,-5) (7, -3) (8, -1) (9, 1)
• (2, -2) (5, 9) (5, -7) (1, 4)

Is the relation a function? Why or why not?

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

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

• Not a Function

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}

Identify the range of the following relation:

• {-6, 14, 2, 28}
• {-6,14, 0, 32, 2, 38, 4,44}
• {-6, 0, 2, 4}
• {14, 32, 38, 44}
