Let even function f (x) satisfy f (x) = x ^ 3-8 (x > = 0), if f (X-2) > 0, then the value range of X is? Did you answer that before? I can't see it. Can you answer it again

Let even function f (x) satisfy f (x) = x ^ 3-8 (x > = 0), if f (X-2) > 0, then the value range of X is? Did you answer that before? I can't see it. Can you answer it again

f(2)=0 f(x-2)>2
/x-2/>2
x> 4 or X

Which of the following functions are odd or even and which are not odd or even? F (x) = x & # 178; + 1 f (x) = x & # 178; + 2x + 1

The first is even function because f (x) = f (- x) is even function, and the second is nothing because f (- x) = - f (x) is odd function

Why is f (x) = x & # 178; (x ≥ 0) a non odd non even function

Whether it is an odd or even function, the definition requires the domain to be symmetric about x = 0. The domain of this function does not satisfy the definition, so it is a non odd and non even function
