Domain and range problem?

Question

Find the range of the following functions.
y=x^3; domain A = {xER | -3 is less and equal to x i less and equal to 2}

Find the domains
1. G(x) = x/(3x-5)
2. h(x) = sqr root of (4+x^2)

Answer 1

0) range : {x e R | -9 <= y <= 8}
1) {x e R | x <5/3 v x> 5/3}
1) R
