Inverses and Radical Functions · Exercise 6

For the radical function $f\left(x\right)=\sqrt{x-2}$, find the following

ⓐ $f\left(3\right)$
ⓑ $f\left(6\right)$
ⓒ $f\left(2\right)$
ⓓ $f\left(1\right)$
ⓔ Why is there a problem with part d? Explain.
ⓕ What do you think is the domain of $f\left(x\right)$? (Hint: think of domain as all the x-values for which we can evaluate $f\left(x\right)$

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