For part a)
when I want to find the CDF, don't I simply take the indefinite integral of e^x, multiply it by c and solve for that = 1?
I am unsure of how to take the integral for this, am i correct in saying it is e^x, for all x ?
that would leave me with c* e^x = 1, and c = 1/(e^x), wolfram says there are two separate results, but i am not sure why. and in that case, I would also have two separate results for c. how can that make sense?
for part b) i am unsure as to how to approach the question. could someone please guide me?
As always, your help is very much appreciated and invaluable.
Thanks
