Determine which of the following graphs does not represent a function.

let's recall the vertical line test, it's a function if when dropping a vertical line on the graph, it only touches it once on the way down.

Check the picture below.

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
