Question

((x, y): y = √x-3The domain of the set above is represented by(x: x ≥ 3)(x: x ≥ 0}(x:x≤ 3)[X: XER)

Answer 1

Given the set below;

`(x,y);y=√(x-3)`

Using a graphing tool, the graph of the function is shown below;

From the graph above,

The domain of the function is from 3 and it tends to infinity, i.e.

`x\ge \:3\:`

Hence, the domain of the set is

`\lbrace x|x\ge3\rbrace`
