Suppose 4 of every 9 dentists recommend Mintyfresh Toothpaste. Suppose eight dentists are chosen (a) exactly five dentists recommend Mintyfresh.

(b) less than seven dentists recommend Mintyfresh.

(c) at least six dentists recommend Mintyfresh.

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.
