When is a function neither odd or even?For example why is x^3/2 neither odd or even?

When the domain is R\{0}, is the range always R+?

How do u find {x:x^3/2>x^2 } and {x:x^-3/2<x^-2}?

is odd. did you mean to say ?

a function f(x) is even if f(-x) = f(x)

a function is odd if f(-x) = -f(x)

otherwise, it is neither

can you solve for x? (is the power 3/2? type clearly) - Jan 3rd 2008, 01:34 AMchaneliman
yea i typed it right

i can't solve x^3/2>x^2 for x. Does it have something 2 do with logs

i understand it till the point u got 0<x<1

then shouldn't it be 0>x if the domain of the square root function is more then or equal to 0
