The only three with a vertex of 0: And, you can actually check this by plugging in numbers. The vertex is at (0,0) for f(x)=|x| (-3,0) for f(x)=|x+3| (6,0) for f(x)=|x-6|
Note: It would be amazibg if you could mark as brainliest, this would really help motivate me to help out more people. Thanks! :)
