# How do determine whether these relations are even, odd, or neither: #f(x)=2x^2+7#? #f(x)=4x^3-2x#? #f(x)=4x^2-4x+4#? #f(x)=x-(1/x)#? #f(x)=|x|-x^2+1#? #f(x)=sin(x)+1#?

Function 1 is even.

Function 2 is odd.

Function 3 is neither.

Function 4 is odd.

Function 5 is even.

Function 6 is neither.

Next time, try and ask separate questions rather than lots of the same at once, people are here to help you, not to do your homework for you.
