Inverse Functions · Exercise 19

Find a domain on which each function $f$ is one-to-one and non-decreasing. Write the domain in interval notation. Then find the inverse of $f$ restricted to that domain.

$f\left(x\right)={\left(x-6\right)}^2$

Its source prints no answer for this problem, so there's nothing to check against.
