y = x^2 -x -6
\n" ); document.write( "factor this equation
\n" ); document.write( "y = (x-3)(x+2)
\n" ); document.write( "a) x intercepts are 3 and -2
\n" ); document.write( "b) turning point is the vertex of this parabola, x part of vertex is
\n" ); document.write( "x = -b/2a = 1/2 = 0.5
\n" ); document.write( "y = 1/4 - 1/2 -6 = -6.25
\n" ); document.write( "turning point is (0.5, -6.25
\n" ); document.write( "d) y intercept is -6
\n" ); document.write( "graph of this parabola is
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+10%2C+x%5E2+-x+-6+%29+\"
