The domain will be how far your graph/function/relation reaches across the x axis. Then the range is how far it stretches up and down the y axis.
So for this relation your domain is x is everything greater than -4 and less than or equal to 5.
And the range is y is everything greater than or equal to -2 and less than 5.
I'm gonna attach a picture as well with the specific notation that we were taught to write with. If your unfamiliar is might be new and confusing but it's actually very simple.
Also I would like to point out that I was specifying greater/less than AND if it was equal to or not. Because from what I know, if there are open or shaded in dots on the graph,
white dots do not mean equal to, so that number it's on will not be included. Only if the dot is shaded then it is included.
Hope I helped! :)
