Macbook air trackpad gestures - Do they work?

I’ve just got this tiny little macbook air for location recording with C 7.5 and I was wondering if gestures on the trackpad have a separate setting or config somewhere.

I was expecting to be able to use the trackpad to zoom in and out with a pinch, adjust q width with a two finger slide, I could go on but I imagine you get the idea…

Sorry if I’m missing something glaringly obvious but does anyone know of a way to utilize these gestures?
