Let R={(10,3), (14,1), (-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={10, 14, -2, 11}

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

    Range={3, 1, -6, -20}

Hence Domain={10, 14, -2, 11} and Range = {3, 1, -6, -20}
