Question

What are the domain and range of the function?

a) Domain: All real numbers; Range: All real numbers.
b) Domain: Positive integers; Range: Negative integers.
c) Domain: All real numbers; Range: Positive integers.
d) Domain: Negative integers; Range: Positive integers.

Answer 1

The domain of the function is all real numbers between 0 and 20, and the range is a single value represented by the constant value of f(x).

Step-by-step explanation:

The domain and range of a function define the set of possible input (domain) and output (range) values of the function, respectively.

Option a) Domain: All real numbers; Range: All real numbers, indicates that the function encompasses all possible real numbers for both input and output. This typically represents a function that spans across the entire real number line in both directions.

Therefore, the correct choice representing a function where the domain includes all real numbers and the range also covers all real numbers is:

a) Domain: All real numbers; Range: All real numbers.
