The domain is represented by the intervals:
(-∞, 0] and (6, ∞)



I hope this helps

Answer:

The domain of the function f(x)=2√x-6 is:

[0,∞)

Explanation:

We have to find the domain of the function f(x)=2√x-6

The domain of the function is all those values of x on which f(x) is well defined.

Here, √x is defined for all the values of x≥0

Since, if x<0 then the value of √x will be imaginary i.e. it is not defined.

Hence, the domain of the function f(x)=2√x-6 is:

[0,∞)
