At the Megaplex theatres you can purchase a Megatub for popcorn for 31.10 including tax. Then, everytime to refill it, you would pay $3.22 including tax. It's about the same size as a large popcorn which costs $8.53 including taxes. Create linear equations from this.

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.
