What are the domain and range of the function f (x) = Squrt x-7+9

domain: x ≥ 7 range: f (x) ≥ 9

Step-by-step explanation:

The domain is the set of values of x for which the function is defined. Those are the values of x that make the square root argument non-negative:

x - 7 ≥ 0

x ≥ 7

__

Since the square root cannot be negative, the sum of it and 9 cannot be less than 9. The range is ...

f (x) ≥ 9
