Question

In the following examples, find the probability density function of Y: (a) Y = 1 - X$^2$ where X has pdf $f(x) = egin{cases} frac{3}{8}(x+1)^2 & -1 < x < 1, 0 & ext{elsewhere.} end{cases}$ (b) Y = $sqrt{2X/lambda}$, where X ~ Exp($lambda$).

          In the following examples, find the probability density function of Y:
(a) Y = 1 - X$^2$ where X has pdf
$f(x) = egin{cases} frac{3}{8}(x+1)^2 & -1 < x < 1, 
0 & 	ext{elsewhere.} end{cases}$
(b) Y = $sqrt{2X/lambda}$, where X ~ Exp($lambda$).

$In the following examples, find the probability density function of Y: (a) Y = 1 - X^2 where X has pdf f(x) = egincases frac38(x+1)^2 -1 < x < 1, 0 extelsewhere. endcases (b) Y = sqrt2X/lambda, where X Exp(lambda).$
