Question

What is the domain of the given function, f(x) = x + 13?

A. All positive numbers
B. All negative numbers
C. There is no solution
D. All real numbers

Answer 1

The domain of the linear function f(x) = x + 13 consists of all real numbers, as there are no restrictions on the input value x.

Step-by-step explanation:

The domain of a function refers to the set of all possible input values that the function can accept. For the linear function f(x) = x + 13, there are no restrictions on the value that x can take. This means that x can be any real number, whether it's positive, negative, or zero. Consequently, the correct answer to this question is D. All real numbers.
