Respuesta :
The domain of h(x)=√x - 3 is [tex]$[3, \infty)$[/tex].
The domain is made up of all the available values that may be used to assess an object and identify ordered pairings in order to create a graph. We situate them on the horizontal axis of the Cartesian plane because the majority of them represent values of the independent variable x.
Given that some function types, such as radicals, require that the radicand be greater than zero, we may determine the domain of a function based on its type. Others do not condition the domain in this way; all integers can evaluate in the function.

In [tex]$\mathbb{R}$[/tex], negative nos. do not have square-root.
So, [tex](x-3) \geq 0, i .$ e.,$x \geq 3$[/tex]. Hence, Domain is [tex]$[3, \infty)$[/tex].
