just a couple problems i need help with, they're in chapter 1 of my calculus book, it's like reviewing for calculus i suppose you could say.

Determine whether the graph of the function is symmetric about they y-axis, the origin, or neither.

1. y= x ^ 1/5

2. y=x^2 -2x - 1

... also

find the domain and range

1. y= |x|-2

2. y=ln(x-3)+1
