I'm having difficulty figuring out what to do with this step function problem:

The instructions are to find the Laplace transform of the given function...

I've looked at the rules for the transformations but I'm perplexed because it seems the should correspond with rather than . This is my last problem from this section and unfortunately I'm stuck. I'm getting exponentials in my answer but it's not perfectly matching up with the given solution.

Thanks for reading!
