I have an Integral that is convergent over the range (-inf, Lambda) where 0< Lambda < 1.
I need to change variables to move this to (0.1, 0.9) in such a way that I do not introduce any poor behavior, such as asymptotes or discontinuities as it needs to be well behaved.
Is there a standard practice for this, like when mapping to unit cube/square?
The integral is like :
## \int_{-\infty}^{\Lambda} e^{3 x} (\Lambda - x)^3 P[x] dx ##
where P[x] is some generic polynomial or unknown smooth function.
Thanks for your help!

EDIT :
I guess I can just use something like
## \Lambda + \frac{(t-\text{tp})}{t-\text{tm}}##
