\n" );
document.write( "y, or the y-coordinate of the vertex = 1

document.write( "STEP 2:
\n" );
document.write( "We can now use 0 (1 less than axis of symmetry value) for x to determine the y value.
\n" );
document.write( "Incidentally, this is the Y-INTERCEPT of the parabola

document.write( "STEP 3:
\n" );
document.write( "As all parabolas are symmetrical about the vertex, we can now use 2 (1 more than axis of symmetry value) for x to

document.write( "determine the y value. The y-value for x = 2 will in this case, be the same y-value when x = 0 was substituted.
