### Maths : What is a function : y=f(x)

In this video I try to explain what a function in maths is. I once asked myself, why keep writing y=f(x) and not just y!?? I've since realised that 'y' can be a function of any number of variables like y=f(x,v,f,e,g,w) so it's always handy to write it like that. Anyway, I try to make this as SIMPLE AND STRAIGHT FORWARD AS POSSIBLE so please enjoy!
