Question

The elements of a function of x are (-6, -7) (-2, -3) and (2, 3) What is the domain of the function?

A: {-7, -3, 3}
B: {-6,-2, 2}
C: {10}
D: {-7, -6, -2}​

Answer 1

B: {-6, -2, 2}

Explanation:

Domain = input values (x-values)

Given elements: (-6, -7) (-2, -3) (2, 3)

The x-values of the given elements are: -6, -2 and 2

Therefore, the domain is {-6, -2, 2}
