Answer:
- domain: x ≥ 7
- range: y ≥ -1
Explanation:
You want to know the domain and range of the function y = √(x -7) -1.
Domain
The domain of the function is the horizontal extent of its graph. The graph of y extends from x = 7 to positive infinity.
the domain is: x ≥ 7
Range
The range of the function is the vertical extent of its graph. The graph of y extends from y = -1 to positive infinity.
the range is: y ≥ -1
