Is this graph a function and how can you tell?

• Yes its a function cause it doesn't cross itself

• No it's not a function because it goes through the origin

• No it's not a function because the x value 4 has y values of  -2 & 2

• No it's not a function because the y value 4 has x values of  -2 & 2

How do you administer a vertical line test.

• You don't only doctor's are allowed to do those

• Draw lines straight across your graph and see if any hit the graph more than once

• Draw lines straight down your graph and see if any hit the graph more than once

• Check to see if the graph is a vertical line( straight up)
