Question

Domain and range from the graph of a discrete relation.

Answer 1

Domain is the x values of the function (left right
range is the y values (up down)

the domain are the x values
the x values are -3, 1, 4
so put {-3,1,4} in the domain box

the range is y values
that is 3,4,0,-3
put {-3,0,3,4} in range box
