CCSS.HSF.IF.A.1

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}

Is this graph a function or not a function? 

• Function
• Not a Function

Which graph does NOT pass the vertical line test? A vertical line should only touch one point at a time, if it is a function.

• Graph 1
• Graph 2
• Graph 3
• Graph 4

Does the graph represent a function? Does it pass the vertical line test?

• 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
• No, because there are not enough dots to tell
• Yes because the dots are all  red

The following is not a function because...

• There are two values that equal 2.

• x = 10 and x = 40 has two values each.

• In the f(x) column, the 5 repeats.

• This table is actually a function.

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.
