    A function is symmetric with respect to the y axis if replacing y with -y does not change the formula. A function is symmetric with respect to the x axis if replacing x with -x does not change the formula. For example, (-x)^2= x^ so y= x^2 is symmetric with respect to the x axis but -y= x^2 is the same as y= -x^2 which is not the same. It is not symmetric with respect to the y axis.
