document.write( "Question 190808: Hi again, John (I don't have the symbols)91311(3186)was nice enough to answer a question but I forgot to explain in detail. 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( "

I'm assuming that the formula is \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 \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the domain is \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.
