You can put this solution on YOUR website!
I couldn't find any formulas that would let you find the minimum of that equation.\r

\n" ); document.write( "\n" ); document.write( "I graphed it instead and saw that the minimum point looks like it is at x = 1.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I took 2 points before and after 1 to test this out.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I chose x = .8 and x = 1.2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "at x = .8, y = 5.0016\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "at x = 1.2, y = 5.0016\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this kind of confirms that the axis of symmetry is at x = 1.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can try other points like .9 and 1.1, and .7 and 1.3.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I suspect the minimum point is at x = 1.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I checked out a website that talked about minimum and maximum points of a polynomial, but I couldn't find anything in there that showed how it could be done other than graphically.\r
