Question

A function is given as a set of ordered pairs (-2, 17), (0, -4), (3, -8), (7, 20). Determine the domain of the function.

A. {-2, 0, 3, 7}
B. {-2, 0, 3, 7, 17, -4, -8, 20}
C. {-2, 0, 3, 7, 20}
D. {-4, -8, 17, 20}

Answer 1

The domain of the function is the set of all x-values from the ordered pairs provided. Hence, the correct answer for the domain is A. {-2, 0, 3, 7}.

Step-by-step explanation:

The function given by the set of ordered pairs (-2, 17), (0, -4), (3, -8), (7, 20) has a domain and range. The domain of a function is the set of all possible input values (x-values) that the function can accept. Looking at the ordered pairs, the first element of each pair represents the x-value. Thus, the domain of this function would be the set of all these first elements.

The correct answer is:

• A. {-2, 0, 3, 7}

This choice lists all the x-values from the ordered pairs, which define the domain of the function.
