Well equations of the form of $\"y=ax%5E2%2Bbx%2Bc\"$ where \"a\" is positive model parabolas that open upward. \r

\n" ); document.write( "\n" ); document.write( "Since the left side of the graph starts high, decreases, and then eventually increases, this means that a parabola would fit the data. So an equation of the form $\"y=ax%5E2%2Bbx%2Bc\"$ should model the data. \n" ); document.write( "
