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}

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? 
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?
