RELATIONS B1

 

Let R={(8,23), (0,1), (-2,-5), (14,-10)}. Find the domain and range of R.

 

solution

 

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

Domain={8, 0, -2, 14}

 

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

Range={23, 1, -5, -10}

 

Hence Domain={8, 0, -2, 14} and Range = {23, 1, -5, -10}
