did you mean?
y = 1/(x^2 + 9)
since it doesn't matter if you use +x or -x,
we have symmetry about the y-axis
y= 1
______
x^2+9
What type of symmetry?

If you meant y = 1/(x^2 + 9), then Replace x with −x and y with −y to check if there is x−axis,y−axis, or origin symmetry.
So,Not symmetric to the x-axis,
Not symmetric to the y-axis, and
Not symmetric to the origin.

Observe the symmetry about the y-axis
