above the x axis a dot on the -2 line up to 2.5, and another dot on -3 line up to 4.5, that's on left side, then right side a dot on 2 line up 2.5, and another on line 3 up to 4.5. Not sure how to figure this is someone is willing to help.

possible answers;
domain: {–3, –2, 0, 2, 3}; range: {4.5, 2.5, 1}
domain: {–3, –2, 2, 3}; range: {4.5, 2.5, 1}
domain: {4.5, 2.5, 1}; range: {–3, –2, 0, 2, 3}
domain: {4.5, 2.5, 1}; range: {–3, –2, 2, 3}

  • algebra -

    the dots are at (-3,4.5),(-2,2.5),(2,2.5),(3,4.5)

    so, domain = {-3,-2,2,3}
    range = {2.5,4.5}

    No given choice fits that. Did you forget a point? say, on the x=0 line up to 1?

  • algebra -

    center dot x=0 line up 1
    to the left of y x=-2 line up to 2.5
    to the left of y x=-3 line up to 4.5

    to the right of y x=2 line up to 2.5
    to the right of y x=3 line up to 4.5

    Does this help?
