What are the domain and the range of function f?

Answer 1

The domain of function f is [0, 20], and the range is a single number that represents the y-coordinate of any point on the horizontal line.

Step-by-step explanation:

The graph of function f(x) is a horizontal line between x = 0 and x = 20, inclusive. Since 0 ≤ x ≤ 20, the domain of function f is the set of all real numbers between 0 and 20, including 0 and 20. Therefore, the domain of function f is [0, 20].

Since the graph of f(x) is a horizontal line, the range of function f is a single value. In this case, the range is the y-coordinate of any point on the horizontal line. Since there is no vertical movement in the graph, the range of function f is a constant value. Therefore, the range of function f is a single number, which is the y-coordinate of any point on the horizontal line.

Answer 2

Range: (negative infinity, 0) U (0, 1/9) U (1/9, infinity)

Domain: (negative infinity, -3) U (-3, 6) U (6, infinity)
