Function image about axisymmetry I'd like to know about the axis symmetry of the function image and how to see it For example, f (x) = 2x ^ 2 + 4 about which axis is symmetric. What about other functions?
First of all, if it is a function, it can only be about Y-axis symmetry or a line that is not y = 0. Because the function requires 1-to-1 or many-to-1, it can not be about X-axis symmetry. Now let's talk about what kind of function is about Y-axis symmetry, that is, if the domain of function definition is about
