The domain is the set of all the first numbers in the ordered pairs:

Domain = {5, -3, 4, -4}

The range is the set of all the second numbers in the ordered pairs:

Domain = {2, 4, 2, 3}

But we don't need to write the 2 twice

Range = {2,4,3}

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

also find g(-3)

That means the second number in the pair that
has -3 for its first number.

Since the ordered pair (-3,4) has -3 as a first number,

then g(-3) = 4, the second number of that ordered pair.
