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}

    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.
