Question

Determine the value of pp so that f(x)=e−xf(x) = $$e^{-x} is a $$probability density function on the interval [p,p+2][p, p + 2].

Accepted Answer

ln⁡(1−e−2)\$$ln(1-e^{-2})      $$

Answer

ln⁡(1+e2)\$$ln(1+e^2)      $$

Answer

ln⁡(2−e−2)\$$ln(2-e^{-2})      $$

Answer

ln⁡(2+e2)\$$ln(2+e^2)      $$
