anonymous · Answer

i am not sure what kind of answer you are looking for
certainly it is a piecwise function
it look like "floor' function, maybe floor of x + 2 or something similar
play around with it and see what you get

anonymous · Answer

You have to write the equation for the graph.

anonymous · Answer

it is not that but here is a picture of floor (x+2) http://www.wolframalpha.com/input/?i=floor+%28x%2B2%29

anonymous · Answer
