RELATIONS E1

 Let R={(7,23), (0,11), (-2,-5), (14,-20)}. Find the domain and range of R.

 

solution

 

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

Domain={7, 0, -2, 14}

 

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

Range={23, 11, -5, -20}

 

Hence Domain={7, 0, -2, 14} and Range = {23, 11, -5, -20}
