Use these ordered pairs to graph the equation.
\1. Draw a coordinate plane.
\2. Plot the points.
\3. Draw a line through these points.
\From the graph, you can see that all points have a y - coordinate of negative 2 or greater, so the range of the function .
The range of the function is
and its graph is
