Homework Statement
Let X be an RV of the continuous type, and let Y=g(X) be defined as g(x)=1 if x>0, and =-1 if x<=0. Find the distribution of Y.
Homework Equations
P(Y <= y) = P(X belongs to g^(-1)(-inf, y])
The Attempt at a Solution
I'm really not too sure what to do here so any help would be tremendously appreciated. For other questions where g is differentiable and the derivative is either <0 or >0 i know that Y will be a continuous RV and the expression for the PDF but here I'm confused.
