SpletCDF (y) = P (Y < y) = P (X^2 < y) = P ( X < sqrt (y)) = P ( -sqrt (y) < X sqrt (y) ) I'm not sure what that is in terms of CDF (x) but we can differentiate CDF (x) to get PDF (x). Then just integrate PDF (x) with bounds sqrt (y) and -sqrt (y) and the function you get should be CDF (y). Reply 2 13 years ago OP gangsta316 What is CDF (x)? SpletPlug components into the PDF Transformation formula above to get a transformed PDF of : \begin{align} f_Y(y) = \frac{2}{(y-1)^2} \quad \text{for} \quad 3 \leq y \lt \infty \end{align} Remembering to use transformed lower and upper bounds, we integrate to get the CDF. Line 3 employs u-substitution to simplify the integration:
