Question

What is the domain of the following function? {5, 16} all real numbers {-3, 3, 5, 9, 16} {-3, 3, 5, 9}

Answer 1

The domain of a function with a horizontal line defined for 0 ≤ x ≤ 20 is the set of all real numbers between and including 0 to 20.

Step-by-step explanation:

The domain of a function refers to the set of all possible input values (x-values) for which the function is defined. In the case where we have a function f(x) that is a horizontal line and is defined for 0 ≤ x ≤ 20, the domain is the set of all real numbers between and including 0 to 20. Therefore, the domain of this function is 0 ≤ x ≤ 20, which means all real numbers from 0 to 20.
