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

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