Question

Move the slider on the graph on the right to graph each function:

For the function: y = StartRoot x minus 7 EndRoot + 1

The domain is : x ≥

The range is: y ≥

Answer 1

Answer: domain: 7

range: 1

Explanation:

Answer 2

• domain: x ≥ 7 . . . [7, ∞) in interval notation
• range: y ≥ 1 . . . [1, ∞) in interval notation

Explanation:

You want the domain and range of the function y = √(x -7) +1.

Domain

The domain is the horizontal extent of the graph. The graph of the given function extends to the right from x=7, which is included in the solution set.

The domain is x ≥ 7.

Range

The range is the vertical extent of the graph. The graph of the given function extends upward from y=1, which is included in the solution set.

The range is y ≥ 1.
