Question

What is the range of:

Answer 1

\[f ^{-1}\] when \[f(x)=\sqrt{x-5}\]

Answer 2

And first, find \[f ^{-1}\]

Answer 3

range of the inverse or of f(x) ?

Answer 4

Yes

Answer 5

But first find the inverse of f(x)

Answer 6

y = \(\sqrt{x-5}\)
\(y^2 = x - 5\)
x = \(y^2 + 5\)
\(f^{-1} (x) = x^2 + 5\)

Domain of f equals range of inverse of f.
Find the domain of f.

Answer 7

I don't know how do do that part

Answer 8

I will draw it...

Answer 9

domain of f(x) = All real numbers 4<?
