Question 287736: This is a two-part problem.

For +f%28x%29+=+sqrt+%28+1-2x+%29+ +g%28x%29+=+-x%2B3+

A) Find (FºG)(x)

B) Find the domain of (FºG)(x)


What I have so far, which I am not totally sure about it:
(FºG)(x) = +sqrt+%28+1-2%28-x%2B3%29+%29+ simplified into +sqrt+%28+2x-5+%29+

Is that correct for step A)? And how do I find the domain for step B)?

A) A looks good.
B) What can x be? And what can't x be?
