\n" ); document.write( "this is what I have so far:\r
\n" ); document.write( "\n" ); document.write( "f(x) =2x^2 +2
\n" ); document.write( " =2(x^2 +1) +2
\n" ); document.write( "f(x) = 2(x^2+1+.5-.5)+2
\n" ); document.write( "=2(x+2+1)+3(.5)+2
\n" ); document.write( "=2(x+3)^2 + 3.5\r

No, not on the right track.
\n" ); document.write( "To get x-intercepts, set f(x)=y=0 and solve for x.
\n" ); document.write( "\"0=2x%5E2+%2B2\"
\n" ); document.write( "Well there are no x such that when you square them and add 2 will give you zero. There are no x-intercepts for this parabola.
\n" ); document.write( "It never crosses the x-axis.
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "To get the y-intercept, set x=0 and solve for y.
\n" ); document.write( "\"y=2%280%29%5E2%2B2\"
\n" ); document.write( "\"y=2\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "You can find the axis of symmetry and vertex by completing the square.
\n" ); document.write( "\"y=2x%5E2%2B2\"
\n" ); document.write( "Actually, it's already in vertex form,
\n" ); document.write( "\"y=2%28x-0%29%5E2%2B2\"
\n" ); document.write( "So the vertex is at (0,2) and it opens upwards.
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "To get other points, just pick an x and calculate y.
\n" ); document.write( "\"x=0+%2B-+1\", \"y=2%281%29%5E2%2B2=4\"
\n" ); document.write( "\"x=0+%2B-+2\", \"y=2%282%29%5E2%2B2=10\"
