Respuesta :

The domain is (-โˆž,โˆž) and the range is [-2,โˆž)

How to determine the domain and the range?

From the graph, we can see that the x values extend at both sides of the graph.

This means that the domain is the set of real values i.e. (-โˆž,โˆž)

However, the minimum y value is -2 and it increases from their

This means that the range is [-2,โˆž)

Hence, the domain is (-โˆž,โˆž) and the range is [-2,โˆž)
