Question

What is the domain of f(x)= the square root of 6x

Answer 1

Answer:

$x\geq 0$

Step-by-step explanation:

The domain of a function $f(x)$ is all $x$ value for which the function is defined.

In $f(x)=\sqrt{6x}$ we have to choose our values of $x$ such that the square root is not negative because then $f(x)$ will be a complex number; therefore for $x\geq 0$,  $f(x)$ is defined and so $x\geq 0$ is he domain of the function.
