Let x be a continuous random variable with density functionf(x)={1−|x|0 for −1

Step-by-step explanation:

For this case we want to find the density function for

And we have the following density function for the random variable X:

So we can do this replacing

If we apply square root on both sides we got:

And if we integrate we got this:

And replacing we got:

And if we want to find the density function we just need to derivate the pdf like this:

im pretty sure its

(8,15)

step-by-step explanation:

it is x=-4
