#Looking for a function family with specific requirements.

Hi, I'm wondering if anyone on here knows of a function family that can meet these requirements (in the first quadrant):

  • f(t) > 0
  • f(t) goes to infinity as t goes to 0 (from the right)
  • f(t) goes to 0 as t goes to infinity
  • f(t) has a local minimum in the first quadrant

oh that's chill

#

I've asked around in multiple discords and it seems like $\frac{1}{x}e^{-(x-t)^2}$ works, now just working on adding more parameters in

Is $\frac{a}{x}e^{-b(x-c)^2}$ the most general case that meets my requirements or am I missing something?

there is no "most general case"

#

you can always keep generalizing

#

well, specifically for this gaussian divided by x idea

#

the x could be raised to higher integer powers ig

you have an answer, that's good enough
