Joe is solving real-world problems that involve multiplicative comparisons. For each problem below, he has written the equation he will use to solve it. Look at Joe's equations and decide whether they are written correctly or incorrectly. For each problem, write correct or incorrect. If the equation is incorrect, write the equation he should use to solve it.

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.
