Determine both domain and range The set of ordered pairs (t, m) where m is
the remaining mass of a 500-gram sample
of a radioactive substance that has been
decaying for t hours.

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis
