Continuous random variable X has probability density function defined as
f(x)= 1/4 , -1<x<3
=0 , otherwise
Continuous random variable Y is defined by Y=X^2
Find G(y), the cummulative distribution function of Y
The Attempt at a Solution
G(y) = P(-sqrt(y)<=X<=sqrt(y))
What does this mean? G(Y) is defined as P(-sqrt(y)<=X<=sqrt(y)) for 0<=X<=9 ?
