How do you find the domain and range and is it a function given points ${(2, - 3), (9, 0), (8 m - 3), (- 9, 8)}$ ${(2,-3), (9,0), (8m-3), (-9,8)}$ ?

As explained below

Domain is a set of points {2,9,8m,-9}
Range is a set of points {-3,0,-3,8}

Yes it is a function because none of the points in the domain has more than one image.

How do you find the domain and range and is it a function given points {(2,−3),(9,0),(8m−3),(−9,8)}{(2,-3), (9,0), (8m-3), (-9,8)}?
