y=x^2+2x-8
\n" ); document.write( " $\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+2x+-8%29+\"$ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, y = 2x -8).
\n" ); document.write( "according to the graph it is +4 for the x intercept.
\n" ); document.write( "also if you set y=0 we get the same answer:
\n" ); document.write( "0=2x-8
\n" ); document.write( "2x=8
\n" ); document.write( "x=8/2
\n" ); document.write( "x=4 answer. \n" ); document.write( "
