what is the domain of f(x)= the square root of (x-4) over the set of real numbers?
**
Two restrictions apply to the domain: the √(x-4) and the denominator.
Since there are no variables in the denominator, the only restriction is in the radican:
x-4≥0
domain: x≥4
In other words, the radican cannot be negative
