Question

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

Answer 1

Answer:

Option (A)

Step-by-step 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) = $\frac{220}{x^3}$

To check the given function is odd or even,

f(-x) = $\frac{220}{(-x)^{3} }$

      = $-\frac{200}{x^{3}}$

Therefore, from the definition of even and odd functions,

Function 'f' is an odd function.

Option (A) will be the correct option.
