RELATIONS 3

Let R={(11,3), (0,1), (-2,-6), (11,-20)}. Find the domain and range of R.

solution

For domain we check on the values of x in each point.

Domain={11, 0, -2}

For range we check on the values of y in each point.

Range={3, 1, -6, -20}

 

Hence Domain = {11, 0, -2} and Range = {3, 1, -6, -20}
