Hello there.

I want to have my students graph a function from a table, but they would be using the variable “n” instead of “x”. The code I have works for 2x-4, but not for 2n-4.

```
function("f"): simpleFunction(table27.cellContent(3,2))
And within the graph I have tried both y=f(x) and y=f(n).
```

Any help appreciated,

Valerie
