Question

Write the ordered pairs for the relation. Find the domain and range.

{(–2, 5), (–1, 2), (0, 1), (1, 2), (2, 5)}; domain: {–2, –1, 0, 1, 2}; range: {1, 2, 5}
{(5, –2), (2, –1), (1, 0), (2, 1), (5, 2)}; domain: {–2, –1, 0, 1, 2}; range: {1, 2, 5}
{(–2, 5), (–1, 2), (0, 1), (1, 2), (2, 5)}; domain: {1, 2, 5}; range: {–2, –1, 0, 1, 2}
{(5, –2), (2, –1), (1, 0), (2, 1), (5, 2)}; domain: {1, 2, 5}; range: {–2, –1, 0, 1, 2}

Answer 1

1)

Ordered pairs: { (-2,5), (-1,2), (0,1), (2,5)}

Domain: these are the x-coordinates = {-2, -1, 0, 2}

Range: these are the y-coordinates = { 1, 2, 5}

2) {(5, –2), (2, –1), (1, 0), (2, 1), (5, 2)};

domain: {–2, –1, 0, 1, 2}; wrong it is {1, 2, 5}

range: {1, 2, 5}; wrong it is {-2, -1 , 0, 1, 2}

Answer 2

1)
Ordered pairs: { (-2,5), (-1,2), (0,1), (2,5)}

Domain: these are the x-coordinates = {-2, -1, 0, 2}

Range: these are the y-coordinates = { 1, 2, 5}

2) {(5, –2), (2, –1), (1, 0), (2, 1), (5, 2)};

domain: {–2, –1, 0, 1, 2}; wrong it is {1, 2, 5}
range: {1, 2, 5}; wrong it is {-2, -1 , 0, 1, 2}



Now you can do the others.
