Functional analysis?

My problem:

I have the function
f(r) = \int exp(-r * x) dx

I want to specify r as a linear function depending on x, so
r(x) = ax + b

Now I want in some ways to see what happens to the function "f" if I
change r(x), e.g.
f(r2) with
r2(t) = r(t) + c
or
r2(t) = r(t) + (a-c)(x-n)

What I hope to see is some form of closed form expression so I can see
how sensitive the function is for changing in some parameters.

Any tips how to start?
