Answer:
x > 0
Explanation:
Restriction on x from the numerator.
The radicand cannot be negative.
4x² ≥ 0
x ≥ 0
From the numerator, we get that x must be greater than or equal to zero.
Restriction on x from the denominator.
Since here we have a square root in the denominator, and division by zero is undefined, the radicand must be greater than zero.
3x > 0
x > 0
From the denominator, the restriction includes zero also, in addition to not allowing negative values of x.
Answer: x > 0
