PLS QUICK!!

Given: F = {(0, 1), (2, 4), (4, 6), (6, 8)} and G = {(2, 5), (4, 7), (5, 8), (6, 9), (7, 5)}

Find the common domain of F and G.

{2, 4, 6}
{1, 4, 6, 8}
{0, 2, 4, 6}

Answer 1

• A. {2, 4, 6}

----------------------

Domain is the set of the first points of ordered pairs.

The domain of F is:

• {0, 2, 4, 6}

and the domain of G is:

• {2, 4, 5, 6, 7}

The common domain of the both sets is:

• {2, 4, 6}

This is matching the option A.
