Find more Education widgets in WolframAlpha. Pick a random value x such that x and x are in your domain which I assume here is all of R. F - x - f x Example 1.
Fx x2 square function in mathbbR the calculation is f-x -x2 x2 fx so the square function fx is even.
Trigonometric functions are examples of non-polynomial even in the case of cosine and odd in the case of sine and tangent functions. Fx fx for all x In other words there is symmetry about the y-axis like a reflection. The function is not even. If you end up with the exact same function that you started with that is if f x f x so all of the signs are the same then the function is even.
