Question

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

Answer 1

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

Answer 2

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.

Answer 3

are you worried about a "-" sign under the radical?

Answer 4

there is no radical in the problem i have here

Answer 5

i mean in the answer i sent.
