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.
yes because 1/2= .5
and 6/12= .5 so they are equivalent
