En un gimnasio se observo que beben agua y bebida rehidratante el triple de los que solo toman bebida rehidratante. ademas, toman otras bebidas tantas personas como las que toman solo una de las bebidas mencionadas. si se sabe que 240 toman bebida rehidratante y 200 toman agua calcula a cuántas personas se observo

(el ejercicio es de conjuntos, ayúdenme por favor)

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
