Question

Which of the following relations has a dornain of {-2, 0, 5)?O ((-5, 6), (0, 4), (-2, 1))O ((-2, 3), (0, 1), (-2, 4), (5, 4))O (1-2, 5), (3, 4), (5, 1))O [(4, -2), (3, 0), (2, 5))

Answer 1

Given: A domain of the function is given

`\lbrace-2,0,5\rbrace`

Required: To identify which relation has the domain of {-2,0,5}.

Explanation: The domain of the function is the x-values of the function. From the given relations we see the relation

`\lbrace(-2,3),(0,1),(-2,4),(5,4)\rbrace`

that the x-values of the relation are {-2,0,5}. Hence the domain of the relation option B have the given domain.

Final Answer: Option B is correct
