    The tests for symmetry needed are as follows:

    A function f(x) is symmetric about the y-axis if f(-x) = f(x)

    that is, replace x with -x in the function, if it simplifies to the original function, then it is symmetric about the y-axis

    A function f(x) is symmetric about the origin if f(-x) = -f(x)

    that is, replace x with -x, if the function simplifies to being the negative of the original, then it is symmetric about the origin
