For the given function, the domain is D : { x ≥ 7} and the range is R: { y ≥ 9}
<h3>
How to get the domain and range?</h3>
Here we have a square root, remember that the argument of the square root must be equal or larger than zero, so the domain is such that:
x - 7 ≥ 0.
Solving for x we get:
x ≥ 0 + 7
Then the domain is:
x ≥ 7
To get the range, we evaluate in the minimum of the domain:
f(7) = √(7 - 7) + 9 = 9
Then the range is the set of all values larger than 9, because the function is increasing.
So the range is R: y ≥ 9.

Answer:
In April, the water temperature in the top 5 meters ranges between 18°C to 19°C and in August, the temperature at 15 to 20 meters range from 29.5°C at the top to 26°C.
Step-by-step explanation:
Because there are g(x)=√(x-1) +1 have √ and +1, the values of g(x) can be only positive.
Value under √ should be positive.
x-1≥0
x≥1.
Correct answer is A.
