You can put this solution on YOUR website!
y= -(x+5)(x-3)(x-6)
\n" ); document.write( "The zeroes are x=-5, x=3, x=6
\n" ); document.write( "Mark those points on the x-axis.
\n" ); document.write( "--------
\n" ); document.write( "If you were to multiply out the right side the highest power term
\n" ); document.write( "would be -x^3 and the y=intercept would be at -5*-3*-6=-90
\n" ); document.write( "Therefore as x gets larger y gets very negative
\n" ); document.write( "So off toward the right of x=6 sketch the curve going down
\n" ); document.write( "-----------------
\n" ); document.write( "Also as x gets more and more negative y gets very positive
\n" ); document.write( "So off to the left of x=--5 sketch the curve coming down to the
\n" ); document.write( "x-axis from above.
\n" ); document.write( "---------------
\n" ); document.write( "So, from left to right:
\n" ); document.write( "The curve comes down to x=-5
\n" ); document.write( "It crosses the x-axis at x=-5
\n" ); document.write( "It crosses the y-axis at -90
\n" ); document.write( "it crosses the x axis at x=3
\n" ); document.write( "It turns around and crosses the x-axis at x=6
\n" ); document.write( "It gets more and more negative as x gets more and more positive.
\n" ); document.write( "================
