Answer:
The third graph from left to right
Step-by-step explanation:
The function [tex]f(x)=\left [ x \right ][/tex] is called Greatest Integer Function of x is such that it returns the largest integer less than or equal to x
Some examples of points are (0,0),(0.5,0),(1,1),(1.9,1),(-0.7,-1)
Since our function is
[tex]f(x)=\left [ x \right ]-2[/tex]
We must subtract 2 to the points above like
(0,-2),(0.5,-2),(1,-1),(1.9,-1),(-0.7,-3)
The only graph that complies with such requirements is the third one
