Now, other than being annoyed that this is being asked for an entry-level job at a gas station, what’s the answer? Image credit: IFLScience, using GeoGebraThen there’s linear functions: nx. Image credit: IFLScience, using GeoGebraNext come exponential functions – here we swap around the polynomials to get nx. Image credit: IFLScience, using GeoGebraNow, that’s not an exhaustive list – factorials can actually be beaten by, say, xx, for example – but it’s the basic setup. And if you’re wondering what the answers really are, we can finally prove our case: 3.14π = 36.404, while π3.14 = 36.396.
