## Homework Statement

Consider a continuous random variable X with the probability density function f

_{X}(x) =

^{|x|}/

_{5}, – 1 ≤ x ≤ 3, zero elsewhere.

I need to find the cumulative distribution function of X, F

_{X}(x).

The equation to find the cdf.

## The Attempt at a Solution

F

_{X}(x) = ∫

_{-1}

^{x}

^{-u}/

_{5}du + ∫

_{-1}

^{0}

^{-u}/

_{5}du + ∫

_{0}

^{x}

^{u}/

_{5}du

For some reason, my result is just a constant, but I can't figure out why my equation is wrong?
