Hi, I've tried everything, and I can't solve these. I'm aware that "hints" have been posted to this question before, but they haven't helped and I still can't solve them.
For each property, write inCreasing, Decreasing, Even, Odd, inVertible in that order (alphabetical). For example, if the function is increasing, odd, and invertible, submit "COV". If the function is none of the above, submit "NONE".
f(x)=x^2-2x+3
f(x)=x+1+1/x
f(x)=|x| * sqrt(x)
Please help!
