determine whether the graph of y = x^2 + 9 is symmetric with respect to the x-axis, the y-axis, or the origin.

\n" ); document.write( "--------------
\n" ); document.write( "To answer the question without graphing check the following:
\n" ); document.write( "f(x) = x^2 + 9
\n" ); document.write( "f(-x) = (-x)^2+9 = x^2+9
\n" ); document.write( "-f(-x) = -[x^2+9] = -x^2-9
\n" ); document.write( "------------------
\n" ); document.write( "Since f(x) = f(-x) you have y-axis symmetry
\n" ); document.write( "Since f(x) does not equal -f(-x) you do not have origin symmetry.
