Question

Suppose that the relation H is defined as follows. H={(7, 1), (1, -8), (-1, -8) Give the domain and range of H. Write your answers using set notation. domain = range = 1

Answer 1

The domain of a set are the x component values for which the set exists

The x- components are {7, 1, -1}

The range are the corresponding values at the y components of the individual sets. This is expressed according to the set notation;

Range = {1, -8}

Hence;

Domain = {7, 1, -1}

Range = {1, -8}
