Ответ:
D.![f(x)=\sqrt{x}-4](/tpl/images/0422/6349/b3b0d.png)
Step-by-step explanation:
Given:
Range is 4 less than square root of domain.
An element of domain is given by the variable 'x'.
An element of range is given by the variable 'y' or
.
Now, an element of range is 4 less than the square root of the element of domain.
So, square root of element of domain is given as:
Subtracting 4 from this will give us the element of the range of the given function.
So,![f(x)=\sqrt{x}-4](/tpl/images/0422/6349/b3b0d.png)
Therefore, the last choice (D) is the answer.
