RELATIONS 2

Let R={(0,3), (4,1), (-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={0, 4, -2, 11}

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

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

Hence Domain={0, 4, -2, 11} and Range = {3, 1, -6, -20}
