y=2x^2-8x. Find the y-intercepts and any x-intercepts.
\n" ); document.write( "To find the y-intercept, let x=0 and solve for y.
\n" ); document.write( "\"y=2%280%29%5E2-8%280%29\"
\n" ); document.write( "\"y=2%280%29-0\"
\n" ); document.write( "\"y=0-0\"
\n" ); document.write( "\"y=0\"
\n" ); document.write( "The y-intercept is (0,0) This is where the graph would cross the y-axis.
\n" ); document.write( ":
\n" ); document.write( "To find the x intercepts, let y=0 and solve for x.
\n" ); document.write( "\"0=2x%5E2-8x\" Factor the GCF, 2x out.
\n" ); document.write( "0=2x(x-4)
\n" ); document.write( "2x=0 and x-4=0
\n" ); document.write( "2x/2=0/2 and x-4+4=0+4
\n" ); document.write( "x=0 and x=4
\n" ); document.write( "The x-intercepts are (0,0) and (4,0)
\n" ); document.write( "Notice that the origin (0,0) is both an x-intercept and a y-intercept.
\n" ); document.write( "Here's what the graph looks like:
