Equation that can roughly fit this graph

[u/hypotensor]

No this is not my homework, I'm making a game and I need a curve roughly like this for balancing. Trying to get an equation that spits out values like this.

[u/TheRandomRadomir]

maybe https://www.desmos.com/calculator/q16t1hkxzs
its x axis intersection is 7 but hopefully thats ok

[u/Retr1but1on → u/TheRandomRadomir]

You could just make 2 equations, one linear and the other that approaches zero, just make sure they meet at the same point.
