Question

What is the domain of the function y = 3√x

Answer 1

Answer:

{x | x ≥ 0}

Step-by-step explanation:

We have the function, $y=3\sqrt{x}$.

Now, for the square root function, the values inside the square root must be positive.

Here, we have that the values of 'x' must be greater than or equal to 0.

i.e. x ≥ 0.

Hence, the domain of the function $y=3\sqrt{x}$ is {x | x ≥ 0}.
