One hundred and eleven cards have all the natural numbers from 1 to 111 written on them. Bryan took the cards with even
numbers, and Betty took the cards with odd numbers. Then they
added up all the numbers on their cards. By how much is one of the
sums greater than the other?

answer: okw

step-by-step explanation:

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.
