Let the random variable x obey the uniform distribution on (- 2,2), then the probability density function of the random variable y = x ^ 2 is

Let the random variable x obey the uniform distribution on (- 2,2), then the probability density function of the random variable y = x ^ 2 is

Fy(y)=P{Y≤y}=P{X^2≤y}
When y
