Graphing radical functionsFirst we need to go the x and y table to see what the points are on the graph. I need help on this!Next-What is the domain and range of this graph

Given equation:
[tex]y=\sqrt{x-4}-2[/tex]the grah of the equation is,
The domain of the equation is,
[tex]x\ge4[/tex]interval notation:
[tex]\lbrack4,\infty)[/tex]The range of the function is,
[tex]f(x)\ge-2[/tex]interval notation is,
[tex]\lbrack-2,\infty)[/tex]
