Question

Suppose that the function g is defined on the interval [-2,2) as follows?
f(x)=

-2 if -2≤x<-1
-1 if -1≤x<0
0 if 0≤x<1
1 if 1≤x<2

Graph the function g

Answer 1

The graph is made up of 4 horizontal line segments of y-coordinates -2, -1, 0, 1 respectively. These segments are disjoint and have a hole on the right, at x = -1, 0, 1, 2

Answer 2

I don't really understand what you mean by that.
