What are the domain and range of each relation? drag the answer into the box to match each relation. a mapping diagram. element x contains negative 2, negative 1, 0, and 2. element y contains negative 4, negative 2, and 2. negative 2 maps to negative 4. negative 1 maps to negative 2 and 2. zero maps to negative 4. two maps to 2. x y −4 −2 −2 1 1 4 4 4 domain: {−4, −2, 1, 4} range: {−2, 1, 4} domain: {−2, −1, 0, 2} range: {−4, −2, 2} domain: {−4, −2, −1} range: {−2, 0, 1}

Domain: {−2, −1, 0, 2} Range: {−4, −2, 2}

Step-by-step explanation:

We have been given a mapping diagram as shown below:

XY

-2-4

-1-2

02

2

For better view, you can check the attached mapping diagram.

From that diagram we have to find domain and range.

Domain contains only x values so domain will be:

Domain: {-2,-1,0,2}

Range contains only y values so range will be:

Range: {-4,-2,2}

We see that only third choice matches obtained values of domain and range.

Hence final answer is  Domain: {−2, −1, 0, 2} Range: {−4, −2, 2}

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
