\n" ); document.write( "You can use \"log(9,(x+6)/2)\" instead of the down arrow to indicate a logarithm base 9.

\n" ); document.write( "(1) y-intercept. The y-intercept is the value of the function when x is 0:
\n" ); document.write( " $\"log%289%2C%286%2F2%29%29+=+log%289%2C%283%29%29+=+0.5\"$

\n" ); document.write( "(2) zero.
\n" ); document.write( " $\"log%289%2C%28%28x%2B6%29%2F2%29%29+=+0\"$
\n" ); document.write( " $\"%28x%2B6%29%2F2+=+9%5E0+=+1\"$
\n" ); document.write( " $\"x%2B6+=+2\"$
\n" ); document.write( " $\"x+=+-4\"$ \n" ); document.write( "
