If I were to graph C(g)=3.03, what is domain and range? I goofed by not saying it was cost per gallon of gasoline. I'm playing beat the clock and I really didn't need to make such a dumb mistake. I guess I'm tired. Thanks for any help. \n" ); document.write( "

You can put this solution on YOUR website!
I'm assuming that the formula is \"C%28g%29=3.03%28g%29\" where \"g\" is the number of gallons of gas and C(g) is the total cost of gas.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since the number of gallons of gas CANNOT be negative (it doesn't make sense if it could), this means that \"g\" must be 0 or some positive number. So this means that \"g%3E=0\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the domain is \"g%3E=0\" which looks like [) in interval notation.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-----------------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now let's say that you don't buy any gas, what is the total cost? The total cost would be zero dollars. So the lowest that the cost can go is $0 (it can't be negative either). \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the cost can be $0 or some positive amount of money. This then makes \"C%28g%29%3E=0\" also.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the range is \"C%28g%29%3E=0\" which looks like [) in interval notation.
\n" ); document.write( "
\n" ); document.write( "
\n" );
