Let me start of by saying I'm not sure if I'm going to be asking this question correctly. I want to find a way to make a formula that grows like a Cumulative distribution function like in this picture maybe about 1.
Let me also reiterate that I remember very little about calculus.
So I want a formula that can get me something that looks like lambda = 1. I want the y axis to start at 0.5 and go all the way up to 3. I also want the x axis to start at 0 and go up to 2,500,000. If you have any idea how to make this possible I would love to know.
Before others asked if I have looked more into this I have. I've looked at some videos trying to get any explanation I could possibly use. I've looked at the formula on the Wikipedia page found here. I just don't know how to interrupt the formula.
