This is the easiest way to graph a simple parabola:
\n" ); document.write( "Choose any small numbers, positive or negative, near 0. Put them in the equation.\r
\n" ); document.write( "\n" ); document.write( "choose: -2,-1,0,1,2
\n" ); document.write( "f(-2)=(-2)^2=4
\n" ); document.write( "f(-1)=(-1)^2=1
\n" ); document.write( "f(0)=0^2=0
\n" ); document.write( "f(1)=1^2=1
\n" ); document.write( "f(2)=2^2=4
\n" ); document.write( " Plot the points:
\n" ); document.write( " $\"graph%28+300%2C+300%2C+-2%2C+2%2C+-4%2C+4%2C+x%5E2+%29\"$ . \r
\n" ); document.write( "\n" ); document.write( "Notice a trend there? The graph will continue like that forever--- it will get larger and larger the higher the x-value you put in. See below:
\n" ); document.write( " $\"graph%28+300%2C+300%2C+-10%2C+10%2C+-100%2C+100%2C+x%5E2+%29\"$ \n" ); document.write( "
