The function is .
The above function is piecewise function.
\Graph the constant function for
. Since
does not satisfy this inequality, began with an open circle at
and draw a horizontal ray to the left.
Graph the constant function for
. Since 2 does not satisfy this inequality, began with an open circle at
and draw a horizontal ray to the right.
The function graph is
The function is defined for , so the domain is
.
The values that are y - coordinates of points on the graph are . So the range is
.
The domain of the function is and its range is
, and its graph is
