if f(x) = $\frac{1}{x} - 1$ , then f(f(1/x)) is
Answer & explanation
Correct answer: option 1
$f(\frac{1}{x}) = \frac{1}{1/x} - 1 = x-1$
$f(f(\frac{1}{x})) = \frac{1}{x-1} - 1 = \frac{2-x}{x-1}$
if f(x) = $\frac{1}{x} - 1$ , then f(f(1/x)) is
Correct answer: option 1
$f(\frac{1}{x}) = \frac{1}{1/x} - 1 = x-1$
$f(f(\frac{1}{x})) = \frac{1}{x-1} - 1 = \frac{2-x}{x-1}$
