Homework Statement
A random variable [tex]X[/tex] is distributed uniformly on [tex][-1,1][/tex]. Find the distribution of [tex]X^2[/tex], its mean and variance.
The Attempt at a Solution
Define a transformation of random variable as [tex]Y=X^2[/tex]. Problem is that the transformation function is not monotonic on the range. If it was just on [0,1] or [-1,0] then it would be monotonic and I could find inverses and hence define the cumulative distribution function, then differentiate to find the distribution.
Is this a correct deduction? Or is there more to it?
