Question

find the domain and range of the following relation {(-2,5), (-1, -3), (-8, 4), (-4, -1), (-7, -9)}

Answer 1

Domain represents all the existing values for x, while the range represents all the existing values for y. All you have to do is list all the first terms in each point for the domain, and do the same with the last terms for the range. (:

Answer 2

Domain is the x-coordinate
therefore Domain X = {-2,-1,-8, -4,-7}

range is the Y-coordinate
therefore Range Y = {5, -3, 4, -1, -9}
