distribution of a function of a random variable problem

a)let X be continuous random variable.Compute the c.d.f. and the density of |x|

b)Let X be a continuouse nonegative random varible with density function fX?Caculate the density of Y=X^n

c)Let X be uniform on (0,1) and K>0. caculate the density of Y=(-1/K)*log(1-X)

can someone help me to solve it , i know it is simple

Re: distribution of a function of a random variable problem

Correct me if I'm wrong, but don't you need to know the p.d.f. of X before you can answer (a)?

the question says you can do it by that way, but there is a direct way to solve it .
