How to determine if function is odd or even

It made my learnings very easy. Amazing app as it allows you to see the solution and explanation of every single one of the math equations or problems you have. I'm taking online math right now and it has been a godsend in helping me understand the homework when I don't want to get tutored every day.

I recommend this app to every student who are in need of high grades, best app ever! This app provides me with the solutions, steps, and answers. I'm telling u right now, really it helped me a lot. Very impressive. Such a wonderful app, it help me alot to solve mathematics questions­â¤.

I love this app for solving maths, it helps me alot with my math homework. Very helpful for if you need to do homework, as someone who doesn't really understand math that well and having something that can help me better my understanding is perfect, im not good in math luckily my friend recommend this app to me.
