Question

Find the domain and range for the following relation. State weather this is a function. (-5,1),(-3,2),(0,3),(1,1),(2,0)

Answer 1

domain : -5,-3,0,1,2
range : 1,2,3,1,0
It is not a function because for two values of x( -5 and 1) we have one value of y which contradicts the definition of function
