Question

Given the function y = 7x - 1 and a range of {-8, 13, 27}, what is the domain of the function?

A) {-1, 2, 4}
B) {-2, 1, 3}
C) {2, 5, 7}
D) {1, 3, 4}

Answer 1

The domain of the function y = 7x - 1 is all real numbers.

Step-by-step explanation:

The domain of a function represents the set of possible input values for which the function is defined. In this case, the given function is y = 7x - 1. To find the domain, we need to determine the values of x that will produce valid outputs for the function. Since there are no restrictions in the given function, the domain is all real numbers. Therefore, the correct answer is A) {-1, 2, 4}.
