If the domain of the square root function f(x) is x<=7, which statement must be true?7 is subtracted from the x-term inside the radical.
The radical is multiplied by a negative number.
7 is added to the radical term.
The x-term inside the radical has a negative coefficient.

Answers

Answer 1
Answer:

Consider the funcion y=√(x). The dmain of this function is \ge 0 and the range is y\ge 0.

Now if x\le 7 you can calculate that

x-7\le 0,\n 7-x\ge 0

and the function y=√(7-x) will have the domain x\le 7 (state this using that expression under the root is \ge 0).

As you can see the x-term inside the radical has a negative coefficient.

Answer: correct choice is D.
Answer 2
Answer: Correct answer is D.

The expression inside the radical must be greater than or equal to zero.

x \leq 7\n0 \leq 7-x\n7-x \geq 0

Therefore, the x-term inside the radical has a negative coefficient.
