The 3rd graph i.e.) the graph with points (-3,-6), (-2,-5), (-1,-4), (0,-3), (1,-2), (2,-1) and (3,0) represents the function f(x)=[x]-3 over interval [-3,3].
Step-by-step explanation:
The given interval is -3 to 3 and substitute these values in the given function.
The given f(x)=[x]-3,
If x= -3,
f(x)= -3-3.
f(x)= -6.
If x= -2, f(x)= -5.
If x= -1, f(x)= -4.
If x= 0, f(x)= -3.
If x=1, f(x)= -2.
If x=2, f(x)= -1.
If x=3, f(x)=0.
The points are (-3,-6), (-2,-5), (-1,-4), (0,-3), (1,-2), (2,-1) and (3,0).
Plot the points in the graph.
