Question

J(x) = 220/x^3 and j-x)=220/(-x)^3

Answer 1

Option (A)

Explanation:

If a function 'f' is an odd function,

f(-x) = -f(x)

If a function 'f' is an even function,

f(-x) = f(x)

In this question given function is,

f(x) =
`(220)/(x^3)`

To check the given function is odd or even,

f(-x) =
`(220)/((-x)^(3) )`

=
`-(200)/(x^(3))`

Therefore, from the definition of even and odd functions,

Function 'f' is an odd function.

Option (A) will be the correct option.
