    Domain and range, as an inequality

    I really don't get how to do this
    I can only figure out the easy straight lines, but when it's a shape I can't really understand it.

    Can somebody give me a REALLY good guide to help me with the graphing and all that.

    I need help with this probelm as well...

    State the Domain and state the range.

    (here are all the corners on the graph)

    (-1,0),(-4,4),(5,0),(2,4)

    Hello Jubbly,

    I'm not really sure where you're having problems. Can you graph the points using the x and y axes to see what the shape is?

    Remember, the domain is the set of x coordinates while the range would be the set of all y coordinates.

    D={-1, -4, 5, 2}

    R={0, 4}
