Find each of the following functions and state their domains: f(x) = v4 - x. (a) 7 g 1 9 = v4-x v12_g domain (-[infinity], - 3] u [3,4] v

a) f(x) = √(4 - x); Domain: (-[infinity], -3] ∪ [3,4]
b) f(x) = -√(4 - x); Domain: (-[infinity], -3] ∪ [3,4]
c) f(x) = √(x - 4); Domain: (-[infinity], -3] ∪ [3,4]
d) f(x) = -√(x - 4); Domain: (-[infinity], -3] ∪ [3,4]
