Answer:

f(x) + f(1/x) = 0

Step-by-step explanation:

Given f(x) = x² - 1/x²

To find f(1/x), we replace x by 1/x in f(x)

So f(1/x) = (1/x)² - 1/(1/x)²

= 1/x² - x²

Then f(x) + f(1/x)

= x² - 1/x² + 1/x² - x²

= 0

Note:

In this type of problem, x must be non-zero because when x becomes 0 (zero), both f(x) and f(1/x) do not exist.

Homeworks for you:

1. Find f(1/x) when f(x) = ax + b

2. Find f(x) - f(1/x) when f(x) = x³ - 1/x³
