We can't tell from the graph whether the left point of each step is included, or the right point. If the left, this is a graph of
  y = 7 + floor(x)

Answer:

Greatest integer function.

Step-by-step explanation:

The given graph  is  of greatest integer  function which is the function that gives the  output in integer number  and is denoted by [ ].

For Example: [0.01]=0

[1.2]=1

Its graph is a discontinuous graph.

This is graph of [x] where x from -3 to 10.
