Hi can anyone help me with this? It’s about even and odd functions but I’m not really good at it, it’s okay if you can only leave an answer but I would appreciate an explanation too. THANKS! I gave these three questions a really high amount of points but please don’t write meaningless answers just to get those points. THANK YOU ALL!
