The correct domain and range for the given data are {-6, -3, 1, 4, 7} and {-2, 0, 1, 4, 7} respectively. Here option B is correct.

Let's analyze the given data to determine the correct domain and range.

The domain is the set of x-values: {-6, -3, 1, 4, 7}

The range is the set of y-values: {4, 1, 7, -2, 0}

Now, let's compare this with the provided options:

A - Domain: {-6, 4, 5, 6} Range: {-7, -6, -4, -2, 4}

Incorrect. The domain contains an extra value (5) not in the given data.

B - Domain: {-6, -3, 1, 4, 7} Range: {-2, 0, 1, 4, 7}

Correct. This matches the determined domain and range.

C - Domain: {-6, -2, 4, 7} Range: {-2, 0, 4, 5}

Incorrect. The domain contains an extra value (-2) not in the given data.

D - Domain: {-3, 1, 4, 7} Range: {-5, 2, 0, 1, 7}

Incorrect. The domain is missing the value -6, and the range contains an extra value (2) not in the given data.

Therefore, the correct answer is:

B - Domain: {-6, -3, 1, 4, 7} Range: {-2, 0, 1, 4, 7}

Complete question:

What is the domain and range?

x | -6 -3 1 4 7

y | 4 1 7 -2 0

A - Domain: {-6, 4, 5, 6}

Range: {-7, -6, -4, -2, 4}

B - Domain: {-6, -3, 1, 4, 7}

Range: {-2, 0, 1, 4, 7}

C - Domain: {-6, -2, 4, 7}

Range:{-2, 0, 4, 5)

D - Domain: {-3, 1, 4, 7}

Range: {-5, 2, 0, 1, 7)
