    Best plot these points out on a graph. That's the fastest way to do this.

    I am not good with graphing period. I do not understand the difference between relation and function

    You just have to put it on a graph...Nothing much. If it passes the vertical line test, then it is a function|dw:1327904685852:dw||dw:1327904713657:dw|

    If it passes twice or more a vertical line anywhere on the graph, then it is a not a function.

    A function is a relation in which a value of input is assigned to only one value of output. In other words, in a "roasted" function, chicken will always be roasted chicken, pork chops will always be roasted pork chops. Chicken can never be roasted chicken and roasted pork chops at the same time. In the relation {(-2,3), (-3,2), (3,2), (2,-3)}, none of the input values are assigned to more than one output value. Hence, the relation is a function.

    A relation is a set of ordered pairs. A function is a relation in which none of the ordered pairs have the same first number.

    Oh ok thank you very much. So if I ordered the pairs they would look like this correct or incorrect. -2 3 -3 2 3 2 2 -3
