Algebra.Com's Answer #271403 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The graph of y=ax^2 + bx + C opens up if a > 0 and down if a < 0. Explain why or how that staement is true. \n" ); document.write( "-------------------------------------- \n" ); document.write( "What happens as x gets more a more positive or more and more negative? \n" ); document.write( "------------------------------------ \n" ); document.write( "1st: You have to understand that the ax^2 overwhelms the effect of bx+c \n" ); document.write( "as x gets more and more positive or gets more and more negative. \n" ); document.write( "---- \n" ); document.write( "2nd: So if a>0, y = ax^2 gets higher and higher if x gets more and more \n" ); document.write( "positive OR if x gets more and more negative. \n" ); document.write( "---- \n" ); document.write( "And if a<0, y = ax^2 gets more and more negative if x gets more and more \n" ); document.write( "positive OR if x gets more and more negative. \n" ); document.write( "------------------------------------------------ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
