profit is revenue minus costs
\n" ); document.write( "4x^2-4x+107
\n" ); document.write( "year 3, 36-12+107=131
\n" ); document.write( "year 4, 64-16+107=155
\n" ); document.write( "year 5, 100-20+107=187
\n" ); document.write( "change in profit from 5-profit from 3 is 56 million
\n" ); document.write( "change in years is 2
\n" ); document.write( "average rate of change is $28 million per year\r
