Answer 1

that. is ugly

Answer 2

use wolfram bro

Answer 3

that dont do you any good.

Answer 4

it always does me good. Hush.

Answer 5

wouldnt x<3 be the domain of the function?

Answer 6

process from the inside out where expression would be greater than or equal to zero to solve for the domain

Answer 7

damn, I have always hated finding domain for composition functions

Answer 8

nevermind.

Answer 9

x can't be greater than 3
x can't be less than -1
x can't be greater than 2

Answer 10

thus x must be between -1 and 2

Answer 12

D {x| 3-x ≥ 0, 2- √(3-x)≥0, 1- √(2-√(3-x)) ≥ 0}

Answer 13

thanks, wolfram

Answer 14

ok, i worked by hand and [-1,2] :D

Answer 15
