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:
4/6
Step-by-step explanation:
You know that there is a total of 6 fruits in the basket.(you can find the total by adding the number of each item together.)
Then you simply find the total amount of oranges(4).
"There are 4 oranges out of the 6 fruits in the basket"/
So, 4/6.

4) (1,3)
This is because in order to keep the ordered pairs a function, x cannot repeat. 1 is the only x that has nor repeated. Hope this helps mate.
