Helo Ann!
I was glad to hear from you so soon, but i am really sorry that you have problems with your parents! I must tell you that I also have a lot of arguments with my parents, but not because of hanging out with my friends. Of course I meet my friends pretty often, we can go for a walk if the weather is fine or we can go to cinema to watch a new film. I have some problems with my parents because I spend too much time at my computer. When I come home from school and finish all my homework, I spend almost all my free time at my computer. My mother doesn't like it ,she thinks that it is not good for my health, especially for my sight. She asks me to swich off the computer and we start arguing! I hate this! But no matter what I say I have to do what she asks me. But I hope that things will start getting better, and I wish you the same!
Take care
Bye

А) f(x)=x(1-x)^2
f(-x)=(-x)*[1 - (-x)]^2] = - x(1-x)^2 функция поменяла знак при замене знака в аргументе. Значит она нечётная
Б) f(x) =x/(x^2) - 4
f(-x)= (-x)/[(-x)^2 - 4] = - x/(x^2) - 4
Функция поменяла знак частично. Значит она ни чётная ни нечётная.
