RELATIONS 1


Let R={(4,3), (9,11), (-2,-6), (17,-20)}. Find the domain and range of R.

solution

For domain we check on the values of x in each point.
Domain={4, 9, -2, 17}

For range we check on the values of y in each point.
Range={3, 11, -6, -20}

Hence Domain={4, 9, -2, 17} and Range = {3, 11, -6, -20}

TRY THIS...............



Let R={(2,3), (-13,8), (-8,-9), (19, -14)}. Find the domain and range of R.
