## anonymous 5 years ago f(x)=-16x^2 What is the inverse function of.. I need the answer plzzzzzz, assume that all variables are positive

1. anonymous

the inverse is $f^{-1}(x)=\sqrt{-\frac{x}{16}}$ typesetting is bad, square root should be over the whole thing.

2. anonymous

if it didn't say "assume that all variables are positive" this function would not be one to one so you would have to restrict the domain to make an inverse.
