Twelfth rebus to exercise your brain on

I think it would be a blast to get paid for creating rebuses!

Suppose you have two (nice enough) functions $f$ and $g$ and a constant $\lambda$ such that $$\lim_{x\to\infty}\frac{f(x)}{g(x)}=\lambda$$ Is it true that $$\lim_{x\to\infty}\frac{f^{-1}(x)}{g^{-1}(x/\lambda)}=1$$ The "reasoning" goes like this: $$\frac{f(x)}{g(x)}\approx\lambda$$ $$f(x)\approx\lambda g(x)$$ $$x\approx f^{-1}(\lambda g(x))$$ $$g^{-1}(x/\lambda)\approx f^{-1}(x)$$ $$\frac{f^{-1}(x)}{g^{-1}(x/\lambda)}\approx 1$$ all of this...
