    Laplace Transformation

    I was attempting the following question,

    f(t) ={k ( 1 - \frac{t}{c}) , 0 <= t < c} and { 0 , t >= c}


    The problem I am having is that I can't understand why are the ranges given ? This is the first question of its type and I am totally confused that where should I start because the questions I attempted before were simple like e^{3t + 4} and I had to just transform them. When I use that same simple transformation technique on the above question the answer comes incorrect.

    Please advice.
