Answer 1

Step-by-step explanation:

Is f(x) a even or odd function f(x) = {(sgnx) ^sgnx} ^n?

Take control of your diabetes.

since sgnx={1, x>0 0 , x=0 -1, x<0

let x>0

f(x)={(sgnx)^sgnx}^n

f(x)={(1)^1}^n

f(x)=1

now,

f(-x)={(sgnx)^sgnx}^n

f(-x)={(-1)^(-1)}^n

f(-x)=(-1)^n

f(-x)= -1 ,since n is odd integer

f(-x)=-f(x)

f(x) is odd function
