what is the y-intercept for x^2-2x-8
\n" ); document.write( "The y-intercept is the point where the parabola crosses the y-axis.
\n" ); document.write( "This value will always be (0, b) where x=0 (if there is a y-intercept).\r
\n" ); document.write( "\n" ); document.write( ".
\n" ); document.write( "So, let x=0 and solve for y:
\n" ); document.write( "y=x^2-2x-8
\n" ); document.write( "y=(0)^2-(0)-8
\n" ); document.write( "y=-8 or point (0, -8)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
