Answer:

Step-by-step explanation:

The key to solving this problem lies in understanding that the domain of the square root function includes ONLY zero or positive numbers.  

In this case, we set 4x - 3 ≥ 0.

Solving for 4x:  4x ≥ 3.  Therefore, x ≥ 3/4.

The domain of the given function is [3/4, ∞ ).
