Tell whether the relation is a function (3,-2)(0,1)(1,,-1)(2,-1)

Have a look at the first elements of each point:  {3, 0, 1, -2, 2}.  Since these are all different, no one x value has more than one y-value associated with it, and thus (3,-2)(0,1)(1,0)(-2,-1)(2,-1) is a function.

it's a function

explanation: the reason why it's a function is when the x's are NOT repeating itself. when it's not a function, it the x's ARE repeating itself.
