Math problem?

Find the relation give the domain and range and indicate which are functions.

<(5,-2) (3,-2) (5,-1)>

Comments

  • in these ordered pairs the x value domain is the first and the y value is the range, second

    Domain {5,3,5}

    Range {-2,1}

    is a relation but not a function as there are two y values {-2,-1} for one x value {5}

  • This relationship is not a function.

    The domain value 5 is paired with two different range values.

  • domai={5,3}

    range={-2,-1}

    not a function as two elements of domain have same image in range set.

  • domain is (5,3,5)

    range is (-2,-1)

    but it is not a function since domain is repeated
