Since you can enter any positive number, or zero, as the number of gallons of gas, this means that the domain is <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=g%3E=0 ALIGN=MIDDLE  ALT=\"g%3E=0\"   DISABLED_style= \"max-width:90%; height:auto;\" >. The range is the set of outputs. It turns out that plugging in all of the possible inputs gives you outputs that are also positive or zero. So the range is <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=C%28g%29%3E=0 ALIGN=MIDDLE  ALT=\"C%28g%29%3E=0\"   DISABLED_style= \"max-width:90%; height:auto;\" > </SPAN>\n" );
