Question 662369: How do you Graph the function with domain of all the real numbers: f(x) = 1 for x ≤ 2, and f(x) = -2 for x > 2

The solid blue (2,1) point, and the blue line to its left
represent the function for (),
and for (.
The open red circle at (2,-2) shows that
point (2,-2) is not part of the function.
All the points with to the right of (2,-2)
are part of the function, with , and .
I drew the lower blue line from (2.1,-2) to {5,-2)
to make it clear that the line does not reach (2,-1),
but of course there are infinity of points with
and just a little larger than that belong to the function.
