High school math. Help summarize the parity of commonly used functions. Such as linear function, quadratic function, cubic function, inverse proportional function and so on?
High school mathematics has a definition of the parity of a function. For odd function, it has f(-x)=-f(x), and the image is symmetrical about the origin. If it is defined at 0, it has f(0)=0, for even functions, it has f(-x)=f(x), and the image is symmetrical about Y, so it is only necessary to judge the parity of the function by definition.
