• y = 2

• none of these

CCSS.HSF.IF.B.5

Is the relation shown a function?

• No, because the x-value 11 is paired with 5 and 8.

• Yes, because each x-value has only one y-value paired with it.

CCSS.HSF.IF.B.5

What is the domain of the following function: ƒ(x)=√(x-10)

• (-∞,∞)

• [10,∞)

• [0,∞)

• [0,10]

Does the graph represent a function?
If you have an x value that has 2 "y" values it is NOT 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
