And how do I start on this? How do I split it up such that I can do it for t>0 and t=<0?

Do I just integrate e^2t between -inf and 0 and integrate e^-t between 0 and inf?

Thanks!

What is |t| when t is negative?

Just split the integral into two parts, one on (-∞,0) and the other on (0,∞).

edit: actually why would that change the sign of the a?

You should really draw [itex]f(t)=e^{|t|}[/itex]. And then give a function that represents f(t) in the first quadrant and f(t) in the second quadrant.

|t| = -t by definition when t is negative.
