Question 287328: This is a two-part problem.
For
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) = simplified into
Is that correct for step A)? And how do I find the domain for step B)?

You can put this solution on YOUR website!
You did part A exactly right!

For the domain, you just have to find the set of acceptable values for x. The function you found in part A has the x inside a square root. Since we must have a non-negative (zero or positive) number inside the square root, the only values we can allow x to be are those those that make 2x-5 non-negative. In other "words"

Solving this:

This describes the acceptable values of x. This is the domain.
