real analysis - Bijection from [0,1] to (1,infty)

I've come across many different versions of this question on here, but not any that map the [0,1] to (1,).



I was thinking that it must be piece-wise defined, since the endpoints 0 and 1 will be the trickiest part of defining the bijection... The only method of doing this that I could come up with would be to possibly show a bijection from [0,1] to (1,2), then construct another bijection from (1,2) to (1,), and then the composition will be from [0,1] to (1,), but I haven't been able to come up with any function that can do this... Any help is much appreciated.
