Answer:
1. f(x) Domain [-3,∞) Range [0,∞)
2. g(x) Domain (-∞,∞) Range [√3, ∞)
3. h(x) Domain [3,∞) Range [0,∞)
4. i(x) Domain (-∞,-√3]∪[√3,∞) Range [0,∞)
5. j(x) Domain (-∞,∞) Range [0,∞)
6. k(x) Domain (-∞,∞) Range [0,∞)
7. f(x) Domain (-∞,∞) Range [3,∞)
Exercise 2 : no there is not an inverse. in about to have an inverse you have to have x and y. yes. if you restrict the domain of the finction so that its 1 to 1 which creates a new function youll have an inverse.
