CCSS.8.F.A.1

CCSS.HSF.IF.B.5

What is the domain of this function?
{(0,2), (3,5), (5,8), (7, 11)}

• {2,5,8,11}
• {0,3,5,7}
• [0,7]
• [2,11]

Is this a function?  Why or why not? 

• Yes, because none of the domain numbers repeated.
• Yes, because none of the range letters repeated.
• No, because 3 goes to A and 4 goes to A.
• No, because A gets used twice.

{(9,8), (7,6), (5,4), (3,2)}

• [3,9]
• [2,8]
• {3,5,7,9]
• {2,4,6,8}

What is the definition of function?

• Has inputs and outputs
• Every input has only ONE output
• Inputs have different outputs every time
• x-values and y-values

What is the domain?

• {-2, -1, 0, 1, 8}
• {3, 5, 7 , 9, 0}
• {-2, -1, 0, 1, 3, 5, 7, 8, 9}

CCSS.HSF.IF.A.1

Which graph does NOT pass the vertical line test?

• Graph 1
• Graph 2
• Graph 3
• Graph 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.
