    density function

    f(t)={ 0 for t<0.5
    ke^-2(t-0.5) for 0.5<t

    how can I find k.
    (is it by integrating)

    are you speaking of a probability density function? , and ...

    for t \geq 0.5 , is the function f(t) = ke^{-2(t-0.5)} ?

    if so ...

    \int_{0.5}^{\infty} ke^{-2(t-0.5)} \, dt = 1

    solve for k.
