Goerge’s page contains twice as many typed words as bill’s page and bill’s page contains 50 fewer words and than charlie’s page. if each person can type 60 words per minute, after one minute, the difference between twice the number of words on bill’s page and the number of words on charlie’s page is 210. how many words did bill’s page contain initially? use a table to organise information.

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.
