Question

Suppose that the relation G is defined as follows.

= {(3,9), (6,9), (4,0)}
Give the domain and range of G.
Write your answers using set notation.

Answer 1

G:{3,4,6}->{0,9}

The pairs represent the input (first number in each pair) and the result (second nu.ber in each pair) for the relation G. for example G(3)=9.

The domain is the set of values that the relation can act upon. The range is the set of the values the results can take
