You can put this solution on YOUR website!
$\"o%28x%29+=+5x+-+x%5E2\"$
\n" ); document.write( "This is a quadratic equation that is in the shape of a parabola. You will need to plot several points in order to get the shape correct. Note the sign on the x^2 term is negative. So the \"U shape\" is pointed down.
\n" ); document.write( "Pick a value of x, then solve for it
\n" ); document.write( "x = 0. o(0) = 5*5 - x^2 = 0 . so one point is (0,0)
\n" ); document.write( "x = 1. o(10 = 5*1 -1^2 = 5-1 = 4. Another point is (1,4)
\n" ); document.write( "and so on. \r
\n" ); document.write( "\n" ); document.write( "Then plot the points and draw the curve. Again geogebra is a nice tool to do this
\n" ); document.write( " $\"graph%28400%2C400%2C-10%2C10%2C-10%2C10%2C+5x-x%5E2%29\"$ \n" ); document.write( "
