for y-intercept put x=0
\n" ); document.write( "for x-intercept put y=0
\n" ); document.write( "in the given equation,
\n" ); document.write( "

\n" ); document.write( "y=4-(x-2)^2
\n" ); document.write( "4-(x-2)^2=0
\n" ); document.write( "4-(x^2+4-4x)=0
\n" ); document.write( "4-x^2-4+4x=0
\n" ); document.write( "-x^2+4x=0
\n" ); document.write( "x(4-x)=0
\n" ); document.write( "x=0 or 4-x=0
\n" ); document.write( "x=0 or x=4
\n" ); document.write( "Then the x-intercepts are: (0,0) and (4,0)
\n" ); document.write( "

\n" ); document.write( "For y-intercept put x=0
\n" ); document.write( "y=4-(x-2)^2
\n" ); document.write( "y=4-(0-2)^2
\n" ); document.write( "y=4-(-2)^2
\n" ); document.write( "y=4-4
\n" ); document.write( "y=0
\n" ); document.write( "So y-intercept is (0,0)
\n" ); document.write( "
