Which of the following represents the range of { (0,-5), (-1,3), (1,2), (2,2), (3,-1), (-5,3) }?
Question 13 options:


{-5,-1,0,1,2,3}


{-5,-1,2,3}


{-1,0,3}


{-5,-1,0,2,3}


{-5,-2,-1,2}

Respuesta :

Answer is {-5, -1, 2, 3}; second answer choice

The range is the set of possible outputs of a relation or function, so we list the y coordinates of each point. Those y coordinates are

-5, 3, 2, 2, -1, 3

Toss out the repeated values and sort from smallest to largest to end up with

-5, -1, 2, 3

surrounding that with curly braces tells the reader that this is a set of values.
